Let be a finitely generated abelian-by-finite group and k a field of characteristic p 0. We show that the Euler class of over k has finite order if and only if every p-regular element of has infinite centralizer in . We also give a lower bound for the order of the Euler class in terms of suitable finite subgroups of . This lower bound is derived from a more general result on finite-dimensional ...

In this paper, we introduce a family of indecomposable finitedimensional graded modules for the twisted current algebras. These modules are indexed by an |R+|-tuple of partitions ξ = (ξ)α∈R+ satisfying a natural compatibility condition. We give three equivalent presentations of these modules and show that for a particular choice of ξ these modules become isomorphic to Demazure modules in variou...

The notions of Busby-Smith and Green type twisted actions are extended to discrete unital inverse semigroups. The connection between the two types, and the connection with twisted partial actions, are investigated. Decomposition theorems for the twisted crossed products are given. 1991 Mathematics Subject Classification. Primary 46L55.
