In this paper,some necessary and sufficient conditions that a finite lattice implication algebra is simple are established.Specially,it is proved that a finite lattice implication algebra L is simple if and only if (L,≤) is a chain,if and only if there exists the unique dual atom in L.Also,it is given that a finite lattice implication algebra with order of a prime number is simple.     

Subdirectly Irreducible and Directly Indecomposable Lattice Implication Algebras

Lattice implication algebra is an algebraic structure that is established by combining lattice and implicative algebra. It originated from the study on lattice-valued logic. In this paper, we characterize two special classes of lattice implication algebra, namely, subdi-rectly irreducible and directly indecomposable lattice implication algebras. Some important results are obtained.

关于格蕴涵代数公理的一个注记

设在一个非空集合L上有一个二元运算→和两个零元运算O与I，除此之外没有其它已知的代数结构，利用这三个运算可以在L上定义一个一元运算′和两个二元运算∨和∧（定义2．1）。本文证明了只要这些运算满足格蕴涵代数的公理（不包括有余格的公理），（L，∨，∧，′）就是一个有泛界O，I的有余格（定理2．2）。因此在定义格蕴涵代数时可以在一个没有任何代数结构的非空集合上定义蕴含运算而不必在一个有泛界的有余格上定义蕴含运算，而且在这两种定义方式中蕴含运算所满足的条件是相同的。

Lattice Ordered Polynomial Algebras

In this paper we define a lattice order on a set F of binary functions. We then provide necessary and sufficient conditions for the resulting algebra F to be a distributive lattice or a Boolean algebra. We also prove a Cayley theorem for distributive lattices by showing that for every distributive lattice , there is an algebra F of binary functions, such that is isomorphic to F and we show that F is a distributive lattice iff the operations and are idempotent and cummutative, showing that this result cannot be generalized to non-distributive lattices or quasilattices without changing the definitions of and . We also examine the equational properties of an Algebra for which , now defined on the set of binary -polynomials is a lattice or Boolean algebra.
