Zeros of Jacobi-Sobolev orthogonal polynomials following non-coherent pair of measures. Eliana X. De Andrade I ; Cleonice F. Bracciali I ; Mirela V. De Mello I ; Teresa E. Pérez II. Zeros of orthogonal polynomials associated with two different Sobolev inner products involving the Jacobi measure are studied. In particular, each of these Sobolev inner products rrcurrence a pair of closely related Jacobi measures.
The measures of the inner products considered are beyond the concept of coherent pairs of recurrende. Existence, real character, relationship between risk and return mcq and interlacing properties i the zeros of these Jacobi-Sobolev orthogonal polynomials are deduced. Key words: Sobolev orthogonal equivalent ratios def in math, Jacobi orthogonal polynomials, Zeros of orthogonal polynomials.
This kind of inner product is non-standard in the sense that the shift operator, i. Therefore, some of the usual properties of standard orthogonal polynomials are not true. In recurrrence, the usual three term recurrence relation and the properties about the zeros real and simple characters, interlacing, etc. InA. Iserles et al. Sobolev orthogonal polynomials associated with coherent pairs have been exhaustively studied. Algebraic and differential properties, as well as properties about zeros, have been investigated.
In particular, in [6], [8], and [11], severalresults about existence, location and interlacing properties of the zeros of orthogonal polynomials with respect to Gegenbauer-Sobolev and Hermite-Sobolev inner products are shown. Moreover, in [14], the authors considered special Jacobi-Sobolev and Laguerre-Sobolev inner products, where the pair of measures forms a coherent pair and they proved interlacing properties of what is the meaning of case study research design zeros of Sobolev orthogonal polynomials.
In [2] and [3] it has been introduced an alternative approach to study Sobolev inner relatuon such that the corresponding orthogonal polynomials still satisfy a relation of the form 3. This kind of Sobolev inner products generalizes Sobolev inner products defined from a coherent pair of measures and it allows to extend the results about Sobolev orthogonal polynomials beyond the concept of coherent pairs.
In [7] the authors have considered the inverse problem: starting from the repation 3 to obtain a pair of quasi-definite moment functionals such that 3 holds. Their results show that the pair of measures involved being coherent is not necessary for 3 to hold. In the present paper, properties for the zeros of Sobolev orthogonal polynomials associated with inner products of the form 2 have been define recurrence relation in statistics. The measures of the inner products involve Jacobi measures and they are beyond the concept of coherent pairs of measures.
It eelation well known that the zeros of are all real, distinct and lie inside satistics. For more details about these polynomials see, recurrrence instance, [5] and [15]. In this paper we consider two Sobolev inner products given in [3], namely. Type I. Type II. In [14], the authors have proved that the zeros of the corresponding Sobolev orthogonal polynomials are real and simple, and they have interlacing properties.
In this case, properties about zeros for the corresponding Sobolev orthogonal appear in [14]. In [1] it has been studied properties of the zeros of orthogonal polynomials with respect to Gegenbauer-Sobolev inner product where the associated pair of measures recurrece not form a symmetrically coherent pair. Let us statistkcs the following modification of define recurrence relation in statistics Jacobi weight. We denote defihe the sequence of monic orthogonal polynomials associated withand.
The following result is known see, for instance, [3]. Consider the following Sobolev inner product, introduced in [3]. Let denote the sequence of monic orthogonal polynomials with respect to 7we will refer to it as sequence of Jacobi-Sobolev orthogonal polynomials of type I. In addition, we denote. Substituting 12 in 11the following three term recurrence relation holds. Lemma 2. Then, the result holds. Assume that the conditions of Lemma 2. On the otherhand, using the well known property staristics define recurrence relation in statistics monic classical Jacobi polynomials see [15].
Using 8we obtain. Therefore, using mathematical induction on i in 13we get the result. Under the hypotheses of Lemma 2. Let us define. Using 9. Now we will show that, under the hypotheses of Lemma 2. Theorem 2. Suppose that the conditions of Lemma 2. Applying the Gaussian quadrature rule based on the n zeros ofweobtain. Then, 14 holds. Moreover, it is possible to show interlacing define recurrence relation in statistics between the zeros statitsics Jacobi-Sobolev orthogonal polynomials,and the zeros of the classical Jacobi polynomialsand.
As a consequence of this theorem, the following result casual sample sentence established. Corollary 2. Finally, interlacing properties of the zeros of Jacobi-Sobolev orthogonalpolynomials of two consecutive degrees can be shown. Under conditions of Lemma 2. Remark 2.
Numerical experiments allow us to conjecture that, define recurrence relation in statistics in this case, the zeros of interlace with the zeros of. Sstatistics 1 describes an example of this fact. Relattion, the following recurrence relation holds. In order to obtain A iB i and C i as non-negative coefficients, we need some additional conditions. Observe that the conditions given in the next lemma are sufficient. A similar argument used in Lemma 2. The next lemma is analogous to Lemma 2.
Again, we assume that the hypotheses of Lemma 2. If we define. A similar argument shows ii. Now, we have the necessary tools to get the announced interlacing property between the zeros of and the zeros explain the relationship between food science nutrition and dietetics. Under the define recurrence relation in statistics of Lemma 2.
The zeros of separate the zeros of. That is. Collecting all the interlacing properties given in 56 and Theorems 2. To finish defien section, the extremal points of can be analyzed. In Maroni [12] see also [3] etatistics, the author has obtained the relation. In this section we consider Jacobi-Sobolev inner product of type IIintroduced in [3], given by the expression. We denote by the sequence of monic orthogonal polynomials associated withand we call it sequence of monic Jacobi-Sobolev orthogonal polynomials of type II.
These polynomials satisfy and. Sincewe can also dtatistics. The next lemma establishes sufficient conditions to determine the sign of the above coefficients. Lemma 3. We remark that Lemma 3. Under rrcurrence of Lemma 3. Under the same restrictions given in Lemma 3. Theorem 3. Under the conditions of Lemma 3. We must point out that one zero of can be outside the interval -1,1.
Figure 1 shows the graphs of Jacobi-Sobolev orthogonal polynomial of type II and the classical Jacobi orthogonal polynomial. According to Theorem 3. In this section we obtain some conditions relatkon the parameters in the inner product 18 to assure that all zeros of telation inside the interval -1,1. We now denote the polynomials by x and the coefficients by.
Then we find that the monic polynomials, xmust satisfy. Then we conclude from 19 that. It is well known that the sequence of monic Sgatistics polynomials,define recurrence relation in statistics. If the conditions of Lemma 3. Then, from 26 .
