Quasitrivial semimodules. III.
Quasitrivial semimodules. IV.
Almost quasitrivial and critical semimodules are studied.
Quasitrivial semimodules. V.
Critical semimodules over congruence-simple semirings are studied.
Quasitrivial semimodules. VI.
The paper continues the investigation of quasitrivial semimodules and related problems. In particular, endomorphisms of semilattices are investigated.
Quasitrivial semimodules. VII.
The paper continues the investigation of quasitrivial semimodules and related problems. In particular, strong endomorphisms of semilattices are studied.
