Torsion factors of commutative monoid semirings

Miroslav Korbelář

Let be a finitely generated commutative semiring. It was shown recently that if is a parasemifield (i.e. the multiplicative reduct of is a group) then cannot contai…

Congruence-simple matrix semirings

Vítězslav Kala, Tomáš Kepka, Miroslav Korbelář

It is well known that the full matrix ring over a skew-field is a simple ring. We generalize this theorem to the case of semirings. We characterize the case when the matrix semirin…

Congruence-simple multiplicatively idempotent semirings

Tomáš Kepka, Miroslav Korbelář, Günter Landsmann

Let be a multiplicatively idempotent congruence-simple semiring. We show that if has a multiplicatively absorbing element. We also prove that if is finite then…
