We define a group theoretical invariant, denoted by s G , as a solution of a certain set covering problem and show that it is closely related to chl(G), the cohomology length of a p-group G. By studying s G we improve the known upper bounds for the cohomology length of a p-group and determine chl(G)

Let G be a semisimple simply connected algebraic group deΓΏned and split over the ΓΏeld Fp with p elements, G(Fq) be the ΓΏnite Chevalley group consisting of the Fq-rational points of G where q = p r , and Gr be the rth Frobenius kernel of G. This paper investigates relationships between the extension
group of linear automorphisms of A . In this paper, we compute the multiplicative n β · Ε½ G . structure on the Hochschild cohomology HH A of the algebra of invariants of n β · Ε½ G . G. We prove that, as a graded algebra, HH A is isomorphic to the graded n algebra associated to the center of the group al
