Titre / Title: M-Algebras and dyadics . Axioms and some properties
Abstract : This paper is devoted to the definition of M-algebras, study of some elementary properties and questions of representation. k being some fixed integer, we define an M-algebra of order k as a pair L = ( T , s ) where T is a distributive lattice with 0 and 1 and s = (e1, ..., ek) some k-uple of elements of T such that every element of T admits exactly one inf- sup representation with respect to s, in the following sense : on one hand , the components belong to the center of T ; on the other hand , whenever we have e r „ e s in the frame, we must have the converse relation x s „ x r on the components. A dyadic is an M-algebra which center is the minimum sublattice < 2 > = {0 ,1 } . Boolean and Postian algebras are simple peculiar cases of M-algebras. We define the characteristic associated to s which is a connected preorder relation . We prove that , with any given connected preorder relation R , we can construct an M-algebra with R as its characteristic.
