Generalized and mixed type Gegenbauer polynomials
Using the integral representation method and the monomiality principle (see e.g.[\textit{G. Dattoli}, Advanced special functions and applications. Proceedings of the workshop, Melfi, Italy, May 9-12, 1999. Rome: Aracne Editrice. Proc. Melfi Sch. Adv. Top. Math. Phys.

A Generalization of Gegenbauer Polynomials and Bi-Univalent Functions
Three subclasses of analytic and bi-univalent functions are introduced through the use of q−Gegenbauer polynomials, which are a generalization of Gegenbauer polynomials. For functions falling within these subclasses, coefficient bounds a2 and a3 as well as Fekete–Szegö inequalities are derived. Specializing the parameters used in our main results leads

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.

Criterion for polynomial solutions to a class of linear differential equation of second order [PDF]
We consider the differential equations y''=\lambda_0(x)y'+s_0(x)y, where \lambda_0(x), s_0(x) are C^{\infty}-functions. We prove (i) if the differential equation, has a polynomial solution of degree n >0, then \delta_n=\lambda_n s_{n-1}-\lambda_{n-1}s_n ...

Explicit solution of the quantum three-body Calogero-Sutherland model [PDF]
Quantum integrable systems generalizing Calogero-Sutherland systems were introduced by Olshanetsky and Perelomov (1977). Recently, it was proved that for systems with trigonometric potential, the series in the product of two wave functions is a ...

Dimensional Reduction for Conformal Blocks [PDF]
We consider the dimensional reduction of a CFT, breaking multiplets of the d-dimensional conformal group SO(d+1,1) up into multiplets of SO(d,1). This leads to an expansion of d-dimensional conformal blocks in terms of blocks in d-1 dimensions.

The affine group and generalized Gegenbauer polynomials
Let \((\xi_1,\xi_2)\) denote a basis of the Lie algebra \(\mathbb{L}\) of the affine group with commutator relation \([\xi_1,\xi_2] =\xi_2\). Representing \(\mathbb{L}\) by the action on polynomials leads to the investigation of operators of the following type: Put \(\xi_1= x\cdot D+\alpha\) (for some constant \(\alpha)\), i.e. \(\xi_1x^n= (n+\alpha) x^

On generalization of extended Gegenbauer polynomials of two variables
Recently, many extensions of some special functions are defined by using the extended Beta function. In this paper, we introduce a new generalization of extended Gegenbauer polynomials of two variables by using the extended Gamma function. Some properties of these generalized polynomials such as integral representation, recurrence relation and ...
