PROPER HYPERSUBSTITUTIONS OF VARIETIES OF PSEUDO-COMPLEMENTED SEMILATTICES
Klaus Denecke, Ratana Srithus · Asian-European Journal of Mathematics · 2013
We determine all V-proper hypersubstitutions for the variety of pseudo-complemented semilattices. Moreover, for any monoid [Formula: see text] of hypersubstitutions we will give the greatest M-solid variety of pseudo-complemented semilattices.
