Abstract

A ring RR with center CC is said to be \textit{centrally essential} if the module RCR_C is an essential extension of the module CCC_C. In the paper, we study groups whose group algebras over fields are centrally essential rings. We focus on the centrally essential modular group algebras of finite groups over fields of nonzero characteristic.
