An overpartition analogue of the $q$-binomial coefficients

Combinatorics 2014-12-30 v2 Number Theory

Abstract

We define an overpartition analogue of Gaussian polynomials (also known as qq-binomial coefficients) as a generating function for the number of overpartitions fitting inside the M×NM \times N rectangle. We call these new polynomials over Gaussian polynomials or over qq-binomial coefficients. We investigate basic properties and applications of over qq-binomial coefficients. In particular, via the recurrences and combinatorial interpretations of over q-binomial coefficients, we prove a Rogers-Ramaujan type partition theorem.
