Abstract

Let RR be a commutative ring with unity and CC be an RR-coalgebra. The ring RR is clean if every rR r\in R is the sum of a unit and an idempotent element of RR. An RR-module MM is clean if the endomorphism ring of MM over RR is clean. Moreover, every continuous module is clean. We modify this idea to the comodule and coalgebra cases. A CC-comodule MM is called a clean comodule if the CC-comodule endomorphisms of MM are clean. We introduced continuous comodules and proved that every continuous comodules is a clean comodule.
