A recursive formula for the number of semi-Heyting algebras definable on a finite chain

Luiz F. Monteiro, Juan Manuel Cornejo, Ignacio D. Viglizzo

We provide a recursive construction of all the semi-Heyting algebras that can be defined on a chain with elements. This construction allows us to count them easily. We also com…
