Some results on L-algebras

In this article, we intend to investigate different types of L -algebras and provide finite and infinite examples of them. Then, we state the concept of ideal in L -algebras, equivalence definitions and examples of it, and introduce different types of ideals, including positive implicative and implicative ideals, and examine definitions equivalent to them and the relationship between them. In addition, we define the quotient structure made by different kind of ideal, and we show that if L is a CKL -algebra and I is a commutative ideal of L , then L I is a commutative BCK -algebra.
