Principal Ideals in the Congruence Semilattice of a Path
Autors:
Fomina Evgenia Olegovna, Saratov State University
Abstract:
It is proven that principal ideals generated by congruences of a path having the same type are isomorphic lattices. The number of elements, atoms and coatoms is found for the principal ideal generated by a given congruence of a path.
