The subject matter of this paper is a study of representations of the full matrix semigroups M (n, p) of n x n matrices with entries in the prime field Zp over a field of characteristic p> 0. Moreover the bulk of it is concerned with a rather classical case of them, namely, the representations of M (n, p) afforded by the spaces of homogenous polynomials. Let B be an n-dimensional vector space over 2,. M (n, p) acts naturally on B. Having fixed a basis x1,..., x, for B we simply identify M (n, p) with the set of all linear transformations on B, Let us fix a ground field k of characteristic p. The action of iW (n, p) on B can be lifted uniquely to the action on IV (l)= k@ B. w”’is simply the vector space of all linear forms in x1,..., X, over k. More generally we form IV@), the vector space of all homogeneous polynomials of degree d in x,,..., X, over k, and lift the natural representation of M (n, p) to tid), d= i, 2,.... These M (n, p) modules WCd’are the main object of our study. More exactly we will tackle here the following problem: Under what conditions on d and n the lattice of all M (n, p)-submodules of W “‘) is distributive? Put differently the problem is to find out when IV (d) and every of its factors are square free.
