    Free‐Decomposability in Varieties of Semi‐Heyting Algebras.Manuel Abad, Juan Manuel Cornejo & Patricio Díaz Varela - 2012 - Mathematical Logic Quarterly 58 (3):168-176.
    In this paper we prove that the free algebras in a subvariety equation image of the variety equation image of semi-Heyting algebras are directly decomposable if and only if equation image satisfies the Stone identity.

    Varieties of Three-Values Heyting Algebras with a Quantifier.Manuel Abad, J. P. Diaz Varela & L. A. Rueda - 2000 - Studia Logica 65 (2):181-198.
    This paper is devoted to the study of some subvarieties of the variety Q of Q-Heyting algebras, that is, Heyting algebras with a quantifier. In particular, a deeper investigation is carried out in the variety Q subscript 3 of three-valued Q-Heyting algebras to show that the structure of the lattice of subvarieties of Q is far more complicated that the lattice of subvarieties of Heyting algebras. We determine the simple and subdirectly irreducible algebras in Q subscript 3 and we construct (...)

    Zariski‐Type Topology for Implication Algebras.Manuel Abad, Diego Castaño & José P. Díaz Varela - 2010 - Mathematical Logic Quarterly 56 (3):299-309.
    In this work we provide a new topological representation for implication algebras in such a way that its one-point compactification is the topological space given in [1]. Some applications are given thereof.
