Hypergeometric transformation formulas of degrees 3, 7, 11 and 23
Published in Journal of Mathematical Analysis and Applications, 2015
Abstract: The theory of theta functions is used to derive hypergeometric transformation formulas of degrees 3, 7, 11 and23. As a consequence of the theory that is developed, some new series for 1/π are obtained that are similar to a class investigated by Ramanujan.
