Abstract

Abstract We introduce the subsum polynomial of a partition = (₁, ₂, , ₖ) λ = (λ 1, λ 2, …, λ k) defined by sp (, x) = ₈=₁ᵏ (1+x^ ᵢ) sp (λ, x) = ∏ i = 1 k (1 + x λ i). We study the sum of reciprocals of sp (, x) sp (λ, x) over all partitions of n. We prove arithmetic properties of related polynomials and offer connections to other combinatorial objects.
