Abstract

Distributive implication groupoids as an essential generalization of the implication reduct of intuitionistic logic were introduced and studied by the second author and I. Chajda in [3]. It has been proved that for these algebras ideals, deductive systems and congruence kernels coincide. In the paper the same connection is shown even if the implication groupoid is quasi-distributive.
