A $q$-multisum identity arising from finite chain ring probabilities

Number Theory 2024-07-22 v2 Combinatorics

Abstract

In this note, we prove a general identity between a qq-multisum BN(q)B_N(q) and a sum of N2N^2 products of quotients of theta functions. The qq-multisum BN(q)B_N(q) recently arose in the computation of a probability involving modules over finite chain rings.
