Recent progress in the study of representations of integers as sums of squares

Heng Huat Chan, Christian Krattenthaler

In this article, we collect the recent results concerning the representations of integers as sums of an even number of squares that are inspired by conjectures of Kac and Wakimoto.…

Some new formulas for $π$

Gert Almkvist, Christian Krattenthaler, Joakim Petersson

We show how to find series expansions for $π$ of the form $π = \sum_{n = 0}^{\infty} S (n) / (p n mn) a^{n}$ , where S(n) is some polynomial in $n$ (depending on $m, p, a$ ). We prov…
