Minimal varieties and quasivarieties of semilattices with one automorphism
The authors describe all minimal quasivarieties and all minimal varieties in the variety \(S\) of semilattices with one automorphism (considered as algebras with one binary and two unary operations). They remark that the lattice of varieties contained in \(S\) is uncountable.
