Hypergeometric Functions of 2 × 2 Matrix Argument are Expressible in Terms of Appell's Functions F 4 [PDF]

open access: closedProceedings of the American Mathematical Society, 1978
It is proved that the hypergeometric function of 2 × 2 2 \times 2 matrix argument is expressible as a solution of the partial differential equations for Appell’s function F 4 {F_4} . As a result the first-mentioned function can be written as a sum of two

A Reflection Formula for the Gaussian Hypergeometric Function of Matrix Argument

open access: green, 2020
We obtain a reflection formula for the Gaussian hypergeometric function of real symmetric matrix argument. We also show that this result extends to the Gaussian hypergeometric function defined over the symmetric cones, and even to generalizations of the ...

The affinely invariant distance correlation [PDF]

open access: yes, 2014
Sz\'{e}kely, Rizzo and Bakirov (Ann. Statist. 35 (2007) 2769-2794) and Sz\'{e}kely and Rizzo (Ann. Appl. Statist. 3 (2009) 1236-1265), in two seminal papers, introduced the powerful concept of distance correlation as a measure of dependence between sets ...

Multidimensional Matrix Inversions and Elliptic Hypergeometric Series on Root Systems [PDF]

open access: yes, 2020
Multidimensional matrix inversions provide a powerful tool for studying multiple hypergeometric series. In order to extend this technique to elliptic hypergeometric series, we present three new multidimensional matrix inversions.

Integrals of Four Variables with Statistical Distribution associated with hyper geometric Function of Matrix Argument

open access: yesInternational Journal for Research in Applied Science and Engineering Technology, 2019
: In this chapter, we evaluated ten integrals associated with hypergeometric function of four variables of matrix argument with their statistical distribution. All the matrix involved were real positive definite symmetric of order m x m.

A new multivariable 6-psi-6 summation formula [PDF]

open access: yes, 2006
By multidimensional matrix inversion, combined with an A_r extension of Jackson's 8-phi-7 summation formula by Milne, a new multivariable 8-phi-7 summation is derived.

Gevrey expansions of hypergeometric integrals II

open access: yes, 2019
We study integral representations of the Gevrey series solutions of irregular hypergeometric systems under certain assumptions. We prove that, for such systems, any Gevrey series solution, along a coordinate hyperplane of its singular support, is the ...

Binomial D-modules [PDF]

open access: yes, 2008
We study quotients of the Weyl algebra by left ideals whose generators consist of an arbitrary Z^d-graded binomial ideal I along with Euler operators defined by the grading and a parameter in C^d. We determine the parameters for which these D-modules (i)

Retrotransposon Expression Is Upregulated in Adulthood and Suppressed during Regeneration of the Limb in the Axolotl (Ambystoma mexicanum)

open access: yesAdvanced Biology, EarlyView.
The axolotl's remarkable regenerative abilities decline with age, the causes may include the numerous repetitive elements within its genome. This study uncovers how Ty3 retrotransposons and coexpression networks involving muscle and immune pathways respond to aging and regeneration, suggesting that transposons respond to physiological shifts and may ...
