Cadenes de Sales discretes
Torrens Torrell, Antoni
The Sales algebras are the substract of some positive implicational calculi . As a first aproximation to their representation we study the Sales algebras that are discrete and linear . In this paper we present a caracteritzation of the finite Sales algebras and we give also an infinite discrete Sales algebra such that we can identify with it every linear infinite simple Sales algebra with a penultimate element . The most interes ting result is the first Theorem In it we show that certain elements of the Sales algebras generate finit linear subalgebras of them .
