Anatolij **Dvurecenskij***On a New Construction of Kite Pseudo BL-algebras*

Abstract:

Using two injections lambda, rho :J → I and an l-group G, we define an
algebra whose universum is (G^+)^J below and (G^-)^I up. This universum can
be endowed with a structure to be a pseudo BL-algebra.

Starting with an Abelian group, the resulting algebra, kite pseudo BL-algebra, can be non-commutative, and even a pseudo MV-alegbra or a pseudo BL-algebra with non-commuting two negations.

We present a characterization of subdirectly irreducible algebras and their classification. We show how this construction can be generalized using a basic pseudo hoop instead of an l-group.
