Existence results for solutions of nonlinear fractional differential equations.

Spherical polar coordinates are convenient for the description of 3-dimensional physical systems that posses spherical or near-spherical symmetry; for such systems they are preferred over other coordinate systems such as Cartesian or cylinder coordinates. Spherical harmonics are ubiquitous in atomic and molecular physics. In quantum mechanics they appear as eigenfunctions of squared orbital angular momentum. What is the definition of symmetric wave function, they are important in the representation of the gravitational and magnetic fields of planetary bodies, the characterization of the cosmic microwave background radiation, the rotation-invariant description of 3D shapes in computer graphics, the description of electrical potentials what does it mean if your hard to read to charge distributions, and in certain types of fluid motion.

Completeness implies that this expansion converges to an exact result for sufficient terms. In an approximate non-converged expansion, the expansion coefficients may be used as linear regression parameters, meaning that they may be chosen such that the expanded function gives a best fit to the original function, which means that the two functions will "resemble" each other as closely as possible.

The more spherical symmetry the original function possesses, the shorter the expansion and the fewer fit regression parameters will have to be determined. In German the functions are called "Kugelfunktionen" what is the definition of symmetric wave function sphere functionsand in French they are known as "fonctions harmoniques sphériques", which is equivalent to their English name. The plots show clearly the nodal planes of the functions. The absolute values are meaningless because the functions are not normalized and accordingly the normalization factors are omitted from their definitions.

The notation will be reserved for the complex-valued functions that are normalized to unity. It is convenient to introduce first non-normalized functions that are proportional to the. Several definitions are possible, the first is the one that is common in quantum mechanically oriented texts. Note that the absolute value of m is taken almost everywhere in the following definition:. An alternative definition indicated by a tilde uses the fact that the associated Legendre functions can be defined by invoking the Rodrigues formula for negative m.

Note that nowhere an absolute value of m appears:. The two definitions obviously agree for positive and zero mbut for negative m this is less apparent. It is also not immediately clear that the choices of phases yield the same function. However, below it will be shown that the definitions agree for negative m as well. Use of the following non-trivial relation, which may be proved by invocation of the What is the definition of symmetric wave function equation, and which does not depend on any choice of phase:.

Since the two definitions of spherical harmonics coincide for positive m and complex conjugation gives in both what is considered a portfolio the same relation to functions of negative mit follows that the two definitions agree.

From here on the tilde is dropped and it is assumed that both definitions are equivalent. If the m -dependent phase would be dropped in both definitions, the functions would still agree for non-negative m. However, the first definition would satisfy. The necessary integral is given here. The non-unit normalization of is known as Racah 's normalization or Schmidt 's semi-normalization. It is often more convenient than unit normalization. Unit normalized functions are defined as follows.

One source of confusion with the definition of the spherical harmonic functions concerns the phase factor. In quantum mechanics the phase, introduced above, is commonly used. It was introduced by Condon and Shortley. There is what is the definition of symmetric wave function requirement to use the Condon-Shortley phase in the definition phenomenon meaning in urdu the spherical harmonic functions, but including it can simplify some what is the definition of symmetric wave function mechanical operations, especially the application of raising and lowering operators.

The geodesy and magnetics communities never include the Condon-Shortley phase factor in their definitions of the spherical harmonic functions. In quantum mechanics the following operator, the orbital angular momentum operatorappears frequently. The components of L satisfy the angular momentum commutation relations. The eigenvalue equation can be simplified by separation of variables. In the spirit of the method of separation of variables, the terms in square brackets are set equal to plus and minus the same constant, respectively.

Substitution of this result what is the definition of symmetric wave function the eigenvalue equation gives. This equation has two classes of solutions: the associated Legendre functions of the first and second kind. The functions of the first kind are the associated Legendre functions:. The eigenvalue equation does not establish phase and normalization, so that these must be imposed separately.

This was done earlier in this article. Insertion of the following functions. They give rise to functions known as regular and irregular solid harmonics. See solid harmonics for more details. The group of proper no reflections rotations in three dimensions is SO 3. Meaning of dissipate in english consists of all 3 x 3 orthogonal matrices with unit determinant.

A unit vector is uniquely determined by two spherical polar angles and conversely. Hence we write. Let R be a unimodular unit determinant orthogonal matrix, then we define a rotation operator by. The inverse matrix appears here acting on a column vector in order to assure that this map of rotation matrices to rotation operators is a group homomorphism.

Since this point was discussed at some length in Wigner 's famous book on group theory, [3] it is known as Wigner's convention. Some authors omit the inverse on the rotation and find accordingly that the map from matrices to operators is antihomomorphic i. It can be shown that the rotation operator is an exponential operator in the components of the orbital angular momentum operator L.

It can be shown that they form an irreducible representation of this group. The rotation operator is unitary and the spherical harmonics are orthonormalhence the Wigner rotation matrix is a unitary matrix:. From this unitarity follows the following useful invariance. The rotation of spherical harmonics may be written as follows where the Racah normalized functions appear :.

Substitute in this expression and we find:. Substitution of this rotation matrix, use of group homomorphism and unitarity of D -matrices. That is, the square of the "distance" between f and the expansion. It is common to write somewhat loosely. It is known from Hilbert space theory that the expansion Fourier coefficients are given by. In quantum mechanics one expresses this by stating that the associated Legendre equation is an eigenvalue equation of a Hermitian operator.

Alternatively one can invoke the Peter-Weyl theoremfrom which follows that the Wigner D -matrices are complete, as the rotation group SO 3 is compact. In general Wigner D -matrices depend on three rotation angles for instance Euler angles. Application of the completeness of the D -matrices to functions that do not depend on one of the three angles proves the completeness of spherical harmonics, while noting the relation between what is the definition of symmetric wave function spherical harmonics and the D -matrices pointed out earlier in this article.

There are two proofs: a short one, referred to by Whittaker and Watson [4] p. The analytic proof is skipped and the physical proof is outlined. Under a simultaneous rotation R of two vectors the angle between them is not changed. Choose the rotation R such that the rotated unit vector coincides with the z -axis, and use that the sum over m in the following is a rotation invariant see earlier in this article. Since the angle between the two vectors is invariant under rotation we have. As a corollary Unsöld's theorem [6] is obtained:.

Since the spherical harmonics are complete and orthonormal, one can expand a binary product of spherical harmonics again in spherical harmonics. This gives the Gaunt series. This double integral is called a Gaunt [7] coefficient. By the Wigner-Eckart theorem it is proportional to the 3j-symbol. These conditions constrain the sum over L in the Gaunt series and remove the sum over M. In total the Gaunt coefficient is. Since the transformation is by a unitary matrix the normalization of the real and the complex spherical harmonics is the same.

The real functions are sometimes referred to as tesseral harmonicssee Whittaker and Watson [4] what is the definition of symmetric wave function. Above, at the beginning of this article, the shapes of a few representative tesseral harmonics are shown. Please take a moment to rate this page below. Found a problem?
