A construction for pseudocomplemented semilattices and two applications
M. E. Adams, Matthew Gould · Proceedings of the American Mathematical Society · 1989
A method is given by which pseudocomplemented semilattices can be constructed from graphs. Two consequences of the method are obtained, namely: there exist continuum-many quasivarieties of pseudocomplemented semilattices; for any non-zero cardinal κ \kappa , there exist κ \kappa pairwise non-isomorphic pseudocomplemented semilattices with isomorphic endomorphism monoids.
