Polynomial analogues of restricted multicolor b-ary partition functions
Given an integer base $b\geq 2$, a number $ρ\geq 1$ of colors, and a finite sequence $Λ=(λ_1,\ldots,λ_ρ)$ of positive integers, we introduce the concept of a $Λ$-restricted $ρ$-colored $b$-ary partition of an integer $n\geq 1$. We also define a sequence of polynomials in $λ_1+\cdots+λ_ρ$ variables, and prove that the $n$th polynomial characterizes all $Λ$-restricted $ρ$-colored $b$-ary partitions of $n$. In the process we define a recurrence relation for the polynomials in question, obtain explicit formulas and identify a factorization theorem.
