Almost Semi Heyting Algebras.

In this paper, we define a Quasi Heyting ADL and derive some necessary and sufficient conditions for an SHADL to become a Quasi Heyting ADL.We also define the concept of an Almost Semi Heyting Algebra and derive some equivalent conditions for an ADL (L,⋁,⋀, 0) with a binary operation → and a maximal element m, to become an Almost Semi Heyting Algebra.
