A combinatorial approach to Berkovich type identities

Combinatorics 2024-04-16 v1 Number Theory

Abstract

Motivated by Berkovich's nine qq-binomial identities involving the Legendre symbol (d3)(\frac{d}{3}), we establish a unified form of qq-binomial identities of this type through a combinatorial approach. This unified form includes Berkovich's nine identities as special cases. Many such identities can be also deduced from this unified form.
