## dedicated to professor klaus w. roggenkamp on the occasion of his 60th birthday We introduce a concept of Cohen-Macaulayness for left noetherian semilocal rings (and their modules) which generalizes the corresponding notion of commutative algebra and naturally applies to orders.
Let G be a digraph, that is, a pair of sets consisting of a set of vertices Ž . and a set of directed edges for a more precise definition, see Section 3 . It is an interesting problem to know how to count the Hamilton cycles of G, that is, cycles containing all vertices of G. In this paper, we will
We investigate the transfer of the Cohen᎐Macaulay property from a commutative ring to a subring of invariants under the action of a finite group. Our point of view is ring theoretic and not a priori tailored to a particular type of group action. As an illustration, we discuss the special case of mul
