Members of Bruno J. M�ller's (1934-2014) mathematical community honor his contributions to algebra with papers on the algebraic structures rings and modules. Among their topics are chains in semiprime and prime ideals in Leavitt path algebras, a category of extensions with endomorphism rings that have at most four maximal ideals, modules invariant under monomorphisms of their envelopes, rings in which every unit is a sum of a nilpotent and an idempotent, and direct sums of completely almost self-injective modules.` Annotation �2018 Ringgold, Inc., Portland, OR (protoview.com)
