Kampé de Fériet hypergeometric functions over finite fields

Ryojun Ito, Satoshi Kumabe, Akio Nakagawa +1

Kampé de Fériet hypergeometric functions are two-variable hypergeometric functions, which are a generalization of Appell's functions. It is known that they satisfy many reduction a…

Hypergeometric expressions of -values for a Borweins theta product of weight

Ryojun Ito

In this paper, we consider a modular form of weight 3, which is a product of the Borweins theta series, and express its -values at , and in terms of special values…
