Weak Alg-universality and $Q$-universality of Semigroup Quasivarieties
Original language description
In the study of universality in semigroups varieties it was shown that three finite semigroups paly an important role. The paper brings the proof that quasivarieties generated by two of them are neither relatively algo-universal nor Q-universal, but there exist two semigroups generating the same semigroup variety but such that the quasivariety generated by them is Q-universal.

Slabá alg-universalita a Q-universalita ve varietách pologrup
Czech description
Při studiu universality variet pologrup se ukázalo, že duležitou roli hraíi tři konečné pologrupy. V článku je dokázáno, že kvazivarieta generovaná dvěma z nich není relativně universální ani Q-universální, ale existují konečné pologrupy generující stejnou varietu, ale takové, že kvazivarieta jimi generovaná již Q-universální je
