On the regularity of some subsemigroups of equivalence relation's endomorphism monoid
E. A. Bondar Luhansk Taras Schevchenko State Pedagogical University, Lugansk, Ukraine
Abstract:
For the set of halfstrong (locally strong, quasi-strong) endomorphisms of an equivalence relation graph, the conditions to form a semigroup are found. Thus the answer to the question put by M. Böttcher and U. Knauer's is given. The conditions for regularity of such semigroups are found too.
Keywords:
regularity, semigroup, endomorphism, equivalence.
