Tiling proofs of Jacobi triple product and Rogers-Ramanujan identities

Combinatorics 2022-05-17 v4 Number Theory

Abstract

We use the method of tiling to give elementary combinatorial proofs of some celebrated qq-series identities, such as Jacobi triple product identity, Rogers-Ramanujan identities, and some identities of Rogers. We give a tiling proof of the q-binomial theorem and a tiling interpretation of the q-binomial coefficients. A new generalized k k -product qq-series identity is also obtained by employing the `tiling-method', wherein the generating function of the set of all possible tilings of a rectangular board is computed in two different ways to obtain the desired qq-series identity. Several new recursive q q-series identities were also established. The `tiling-method' holds promise for giving an aesthetically pleasing approach to prove old and new qq-series identities.
