Set theory is the can romantic love be platonic theory of well-determined collections, called setsof objects that are called membersor elementsof the set. Pure set theory deals exclusively with sets, so the only sets under consideration sets class 11 formulas those whose members are also sets.

The theory of the hereditarily-finite sets, namely those finite sets whose elements are also finite sets, the elements of which are also finite, and so on, is formally equivalent to arithmetic. So, the essence of set theory is the study of infinite sets, and therefore it can be defined as the mathematical theory of the actual—as opposed to potential—infinite. The notion of set is so simple that it is usually introduced informally, and regarded as self-evident.

In set theory, however, as is usual in mathematics, sets are given axiomatically, so their existence and basic properties are postulated by the appropriate formal axioms. The axioms of set theory imply the existence of a set-theoretic universe so rich that all mathematical objects can be construed as sets. Sets class 11 formulas, the formal language of pure set theory allows one to formalize all mathematical notions and arguments. Thus, set theory has become the standard foundation for mathematics, as every mathematical object can what is the height to base ratio for scaffolding viewed as a set, sets class 11 formulas every theorem of mathematics can be logically deduced in the Predicate Calculus from the axioms of set theory.

Both aspects of set theory, namely, as the mathematical science of the infinite, and as the foundation of mathematics, are of philosophical importance. Set theory, as a separate mathematical discipline, begins in the work of Georg Cantor. One might say that set theory was born what does asso mean in japanese latewhen he made the amazing discovery that the linear continuum, that is, the real line, is not countable, meaning that its points cannot sets class 11 formulas counted using the natural numbers.

So, even though the set of natural numbers and the set of real numbers are both infinite, there are more real numbers than there are natural numbers, which opened the door to the investigation of the different sizes of infinity. In Cantor formulated the famous Continuum Hypothesis CHwhich asserts that every infinite set of real numbers is either countable, i.

In other words, there are only two possible sizes of infinite sets of real numbers. The CH is the most famous problem of set theory. Cantor himself devoted much effort to it, and so did many other leading mathematicians of the first half of the twentieth century, such as Hilbert, who listed the CH as the first problem in his celebrated list of 23 unsolved mathematical problems presented in at the Second International Congress of Mathematicians, in Paris.

The attempts to prove the CH led to major discoveries in set theory, such as the theory of constructible sets, and the forcing technique, which showed that the CH can neither be proved nor disproved from the usual axioms of set theory. To this day, the CH remains open. Early on, some inconsistencies, or paradoxes, arose from a naive use of the notion of set; in particular, is beetroot a healthy snack the deceivingly natural assumption that every property determines a set, namely the set of objects that have the property.

Thus, some collections, like the collection of all sets, the collection of all ordinals numbers, or the collection of all cardinal numbers, are not sets. Such collections are called proper classes. In order to avoid the paradoxes and put it on a firm footing, set theory had to be axiomatized. Further work by Skolem and Fraenkel led to the formalization of the Separation axiom in terms of formulas of first-order, instead of the informal notion of property, as well as to the introduction of the axiom of Replacement, which is also sets class 11 formulas as an axiom schema for first-order formulas see next section.

The axiom of Replacement is needed for a proper development of the theory of transfinite ordinals and cardinals, using transfinite recursion see Section 3. It is also needed to prove the existence of such simple sets as the set of hereditarily finite sets, i. A further addition, by von Neumann, of the axiom of Foundation, led to the standard axiom system of set theory, known as the Zermelo-Fraenkel axioms plus the Axiom of Choice, or ZFC.

See the. We state below the axioms of ZFC informally. Infinity: There exists an infinite set. These are the axioms of Zermelo-Fraenkel set theory, or ZF. Also, Replacement implies Separation. The AC was, for a long time, a controversial axiom. On the one hand, it is very useful and of wide use in mathematics. On the other hand, it has rather unintuitive consequences, such as the Banach-Tarski Paradox, which says that the unit ball can be partitioned into finitely-many pieces, which can then be rearranged to form two unit balls.

The objections to the axiom arise from the fact that it asserts the existence of sets that cannot be explicitly defined. The Axiom of Choice is equivalent, modulo ZF, to the Well-ordering Principlewhich asserts that every set can be well-ordered, i. In ZF one can easily prove that all these sets exist.

See the Supplement on Basic Set Theory for further discussion. In ZFC one can develop the Cantorian theory of transfinite i. Following the definition given by Von Why are open relationships so popular in the early s, the ordinal numbers, or ordinalsfor short, are obtained by starting with the empty set and performing two operations: taking the immediate successor, and passing to the limit.

Also, every well-ordered set is isomorphic to a unique ordinal, called its order-type. Note that every ordinal is the set of its predecessors. In ZFC, one identifies the finite ordinals with the natural numbers. One can extend the operations of addition and multiplication of natural numbers to all the ordinals. One uses transfinite recursion, for example, why are therapeutic relationships important in mental health nursing order to define properly the arithmetical operations of addition, product, and exponentiation on the ordinals.

Recall that an infinite set is countable if it is bijectable, i. All the ordinals displayed above are either finite or countable. A cardinal is an ordinal that is not bijectable with any smaller ordinal. It starts like this. For every cardinal there is a bigger one, and the limit of an increasing sequence of cardinals is also a cardinal. Thus, the class of all cardinals is not a set, but a proper class.

Non-regular infinite cardinals are called singular. In the case of exponentiation of singular cardinals, ZFC has a lot more to say. The technique developed by Shelah to prove this and similar theorems, in ZFC, what is database system with example called pcf theory for possible cofinalitiesand has found many applications in what is relational algebra and its operations areas of mathematics.

A sets class 11 formulasthe ZF axioms sets class 11 formulas than Extensionality—which needs no justification because it just states a defining property of sets—may be justified by their use in sets class 11 formulas the cumulative hierarchy of sets. Every mathematical object may be viewed as a set. Let us emphasize that it is not claimed that, e. The metaphysical question of what the real numbers really are is irrelevant here. Any mathematical object whatsoever can always be viewed as a set, or a proper class.

The properties of the object can then be expressed in the language of set theory. Any mathematical statement can be formalized into the language of set theory, and any mathematical theorem can be derived, using the calculus of first-order logic, from the axioms of ZFC, or from some extension of ZFC. It is in this sense that set theory provides a foundation for mathematics. The foundational role of set theory for mathematics, while significant, is by no means the only justification for its study.

The ideas and techniques developed within set theory, such as infinite combinatorics, forcing, or the theory of large cardinals, have turned it into a deep and fascinating mathematical theory, worthy of study by itself, and with important applications to practically all areas of mathematics. The remarkable fact that virtually all of mathematics can be formalized within ZFC, makes possible a mathematical study of mathematics itself.

Thus, any questions about the existence of some mathematical object, or the provability of a conjecture or hypothesis can be given a mathematically precise formulation. This makes metamathematics possible, namely the mathematical study of mathematics itself. So, the question about the provability or unprovability of any given mathematical statement becomes a sensible mathematical question. When faced with an sets class 11 formulas mathematical problem or conjecture, it makes sense to ask for its provability or unprovability in the ZFC formal system.

Unfortunately, the answer may be neither, because ZFC, if consistent, is incomplete. InGödel announced his striking incompleteness theorems, which assert that any reasonable formal system for mathematics sets class 11 formulas necessarily incomplete. And neither can its negation. We shall see several examples in the next sections. The main topic was the study of the so-called regularity properties, as well as other structural properties, of simply-definable sets of real numbers, an area of mathematics that is known as Descriptive Set Theory.

What is symbiotic relationship give one example simplest sets of real numbers are the basic open sets i. The sets that are obtained in a countable number of steps by starting from the basic open sets and applying the operations of taking the complement and forming a countable union of previously obtained sets are the Borel sets. All Borel sets are regularthat is, they enjoy all the classical regularity properties.

One example of a regularity property is the Lebesgue sets class 11 formulas : a set of reals is Lebesgue measurable if it differs from what is the real meaning of effective communication Borel set by a null set, namely, a set that can be covered by sets of basic open intervals of arbitrarily-small total length.

Thus, trivially, every Borel set is Lebesgue measurable, but sets more complicated than the Borel ones may not be. Other classical regularity properties are the Baire property a set of reals has sets class 11 formulas Baire property if it differs from an open set by a meager set, namely, a set that is a countable union of sets that are not dense in any intervaland the perfect set property a set of reals has the perfect set property if it is either countable or contains a perfect set, namely, a nonempty closed set with no isolated points.

The projective sets form a hierarchy of increasing complexity. ZFC proves that every analytic set, and therefore every co-analytic set, is Lebesgue measurable and has the Baire property. It also proves that every analytic set has the perfect set sets class 11 formulas. The theory of projective sets of complexity greater than co-analytic is completely undetermined by ZFC.

There is, however, an axiom, called the axiom of Projective Determinacy, or PD, that is consistent with ZFC, modulo the consistency of some large cardinals in fact, it follows from the existence of some large cardinalsand implies that all projective sets are regular. Moreover, PD settles essentially all questions about the projective sets. See the entry on large cardinals and determinacy for further details.

A regularity property of sets that subsumes all other classical regularity properties is that of being determined. We may visualize a run of the game as follows:. Otherwise, player II wins. Further, he showed that if there exists a large cardinal called measurable see Section 10then even the analytic sets are determined. The axiom of Projective Determinacy PD asserts that every projective set is determined.

It turns out that PD implies that all projective sets of reals are regular, and Woodin has shown that, in a certain sense, PD settles essentially all questions about the projective sets. Moreover, PD seems to be necessary for this. Thus, the CH holds for closed sets. More than thirty years later, Pavel Aleksandrov extended the result to all Borel sets, and then Mikhail Suslin to all analytic sets. Thus, all analytic sets satisfy the CH. However, the efforts to prove that co-analytic sets satisfy the CH would not succeed, as this is not provable in ZFC.
