Expected number of real zeros for random linear combinations of orthogonal polynomials [PDF]
We study the expected number of real zeros for random linear combinations of orthogonal polynomials. It is well known that Kac polynomials, spanned by monomials with i.i.d.

Orthogonality of quasi-orthogonal polynomials
A result of P?lya states that every sequence of quadrature formulas Qn(f) with n nodes and positive Cotes numbers converges to the integral I(f) of a continuous function f provided Qn(f) = I(f) for a space of algebraic polynomials of certain degree that depends on n.

Clifford algebra-valued orthogonal polynomials in the open unit ball of Euclidean space
A new method for constructing Clifford algebra-valued orthogonal polynomials in the open unit ball of Euclidean space is presented. In earlier research, we only dealt with scalar-valued weight functions.

Orthogonal polynomials with orthogonal derivatives [PDF]
We are concerned with the following assertion: THEOREM. If {φn(x)} and { φn’(x)} are orthogonal systems of polynomials, then {φn(x)} may be reduced to the classical polynomials of Jacobi, Laguerre, or Hermite by means of a linear transformation on x.

Orthogonal polynomials of dimension –1 in the non-definite case [PDF]
: Orthogonal polynomials of dimension d = −1 are a particular case of vector orthogonal polynomials which are, themselves, a particular case of biorthogonal polynomials.

Representations of orthogonal polynomials
Zeilberger's algorithm provides a method to compute recurrence and differential equations from given hypergeometric series representations, and an adaption of Almquist and Zeilberger computes recurrence and differential equations for hyperexponential integrals.

A set of orthogonal polynomials induced by a given orthogonal polynomial
Given an integern ⩾ 1, and the orthogonal polynomialsπn(·; dσ) of degreen relative to some positive measuredσ, the polynomial system “induced” byπn is the system of orthogonal polynomials\(\{ \hat \pi _{k,n} \} \) corresponding to the modified measure\(d\hat \sigma _n = \pi _n^2 d\sigma \).

Polynomials orthogonal on the semicircle [PDF]
AbstractComplex polynomials {πk}, πk(z) = zk + ···, orthogonal with respect to the complex-valued inner product (f, g) = ∝0πf(eiθ)g(eiθ)dθ are studied. By direct calculation of moment determinants it is shown that these polynomials exist uniquely. The three-term recurrence relation satisfied by these polynomials is obtained explicitly as well as their ...
