Weighted Erdős-Burgess and Davenport constant in commutative rings

preprint2022arXivOpen access

Abstract

Let RR be a finite commutative unitary ring. An idempotent in RR is an element e∈Re\in R with e2=ee^2=e. Let ΨΨ be a subgroup of the group Aut(R){\rm Aut}(R) of all automorphisms of RR. The Ψ−Ψ-weighted Erdős-Burgess constant IΨ(R){\rm I}_Ψ(R) is defined as the smallest positive integer ℓ\ell such that every sequence over RR of length at least ℓ\ell must contain a nonempty subsequence a1,…,ara_1,\ldots, a_{r} such that ∏i=1rψi(ai)\prod\limits_{i=1}^r ψ_i(a_i) is one idempotent of RR where ψ1,…,ψr∈Ψψ_1,\ldots,ψ_r\in Ψ. In this paper, for the finite quotient ring of a Dedekind domain RR, a connection is established between the Ψ−Ψ-weighted-Erdős-Burgess constant of RR and the Ψ−Ψ-weighted Davenport constant of its group of units by all the prime ideals of RR.
