A Construction for Pseudocomplemented Semilattices and Two Applications

M. E. Adams, Matthew Gould
1989 Proceedings of the American Mathematical Society  
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 k , there exist k pairwise non-isomorphic pseudocomplemented semilattices with isomorphic endomorphism monoids.
