We extend past results on a family of formal power series K n,Λ , parameterized by n and Λ ⊆ [n], that largely resemble quasisymmetric functions. This family of functions was conjectured to have the property that the product K n,Λ K m,Ω of any two functions K n,Λ and K m,Ω from the family can be expressed as a linear combination of other functions from the family. In this paper, we show that this is indeed the case and that the span of the K n,Λ 's forms an algebra. We also provide techniques for examining similar families of functions and a formula for the product K n,Λ K m,Ω when n = 1.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
