Hypergeometric functions in arithmetic geometry [PDF]

open access: yes, 2009
textHypergeometric functions seem to be ubiquitous in mathematics. In this document, we present a couple of ways in which hypergeometric functions appear in arithmetic geometry.

Contractions of 2D 2nd Order Quantum Superintegrable Systems and the Askey Scheme for Hypergeometric Orthogonal Polynomials [PDF]

open access: yes, 2013
We show explicitly that all 2nd order superintegrable systems in 2 dimensions are limiting cases of a single system: the generic 3-parameter potential on the 2-sphere, S9 in our listing.

A Feynman integral and its recurrences and associators

open access: yesNuclear Physics B, 2016
We determine closed and compact expressions for the ϵ-expansion of certain Gaussian hypergeometric functions expanded around half-integer values by explicitly solving for their recurrence relations.

On Some Formulas for the Lauricella Function

open access: yesMathematics, 2023
Lauricella, G. in 1893 defined four multidimensional hypergeometric functions FA, FB, FC and FD. These functions depended on three variables but were later generalized to many variables.

Integral representations for a class of triple confluent hypergeometric functions and their applications in boundary value problems

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы
Hypergeometric functions are divided into complete and confluent functions. Srivastava and Karlsson were the first to propose a method for constructing the complete set of triple Gaussian hypergeometric series and compiled a table containing definitions

New Developments on the Theory of Third-Order Differential Superordination Involving Gaussian Hypergeometric Function

open access: yesMathematics, 2023
The present research aims to present new results regarding the fundamental problem of providing sufficient conditions for finding the best subordinant of a third-order differential superordination. A theorem revealing such conditions is first proved in a

Precise Estimates for Differences of the Gaussian Hypergeometric Function

open access: yesJournal of Mathematical Analysis and Applications, 1997
For given \(a,b,c,d\in (0,\infty)\), \(a\leq b\), and \(c< d\), the authors study the problem of comparing the Gaussian hypergeometric functions \(F(a,b; a+b; 1-x^c)\) and \(F(a-\delta, b+\delta; a+b; 1- x^d)\). In particular they solve some open problems by determining \(\sup\{\delta\in (0,\infty): F(a,b; a+b; 1-x^c)< F(a-\delta, b+\delta; a+b; 1-x^d)\

Coefficient Conditions for Starlikeness of Nonnegative Order

open access: yesAbstract and Applied Analysis, 2012
Sufficient conditions on a sequence {ak} of nonnegative numbers are obtained that ensures f(z)=∑k=1∞akzk is starlike of nonnegative order in the unit disk. A result of Vietoris on trigonometric sums is extended in this pursuit.

On the complete perturbative solution of one-matrix models

open access: yesPhysics Letters B, 2017
We summarize the recent results about complete solvability of Hermitian and rectangular complex matrix models. Partition functions have very simple character expansions with coefficients made from dimensions of representation of the linear group GL(N ...

Hilbert inequality and Gaussian hypergeometric functions [PDF]

open access: yesJournal of Mathematical Inequalities, 2009
By using the integral representation of Gaussian hypergeometric function, we obtain Hilbert type inequalities with some fractional kernels and non-conjugate parameters. Such inequalities include the constant factors expressed in terms of hypergeometric functions. Further, we obtain the best possible constants for some general cases, in conjugate case.
