Finite $q$ -multiple harmonic sums with one exceptional index

Hideaki Ishikawa, Takao Komatsu

In this paper, we give explicit expressions about $q$ -harmonic sums on $1 - \dots - 1, A, 1 - \dots - 1$ indices. The case $A = 1$ has been extensively studied, and a variety of identities,…

Some explicit values of a $q$ -multiple zeta function whose denominator power is not uniform

Yuri Bilu, Hideaki Ishikawa, Takao Komatsu

One of the generalizations of multiple zeta values is the $q$ -version, and in the case of finite sums, they may be expressed explicitly in polynomial form. Several results have bee…
