Refined $q$-Trinomial Coefficients and Two Infinite Hierarchies of $q$-Series Identities (1810.12048v2)
Published 29 Oct 2018 in math.NT and math.CO
Abstract: We will prove an identity involving refined $q$-trinomial coefficients. We then extend this identity to two infinite families of doubly bounded polynomial identities using transformation properties of the refined $q$-trinomials in an iterative fashion in the spirit of Bailey chains. One of these two hierarchies contains an identity which is equivalent to Capparelli's first Partition Theorem.
