Abstract
In this paper, we introduce the notion of pseudo-absorbing
comultiplication modules. A full description of all indecomposable pseudo-absorbing
comultiplication modules with finite dimensional top over certain kinds of pullback rings
are given and establish a connection between the pseudo-absorbing comultiplication
modules and the pure-injective modules over such rings.
