摘要:

It is proved that each Schurian algebra is tensor-simple. Let K be a field, for any algebra A denote by  the set of isoclasses of simple A-modules. A module means a left module. If M and N are A- and B-modules respectively, then their tensor product M⊗ N (over K,⊗ means ⊗k) is the module over the tensor product A⊗ B of algebras A and B.

摘要:

We construct the set of generic representations for parabolic subgroups of the complex orthogonal group SO(2n,C) and show that the set Opof generic representations of an arbitrary parabolic subgroup P of SO(2n, C) can be explicitly decribed in terms of unitary representations of some smaller reductive group Gp.

摘要:

This paper is concerned with the problem when an Ore extension R[t, S, D] has the same Goldie rank as the coefficient ring R. It is shown, in particular, that this is the case when either R is non-singular or D is a q-quantized s-derivation satisfying some finiteness conditions.

摘要:

In this paper the concept of cocyclic modules is introduced, and it is used to define coassociated primes and the cosupport of mod-ules. Also it is shown that cocyclic modules are important for proving properties of the set of coassociated primes and the cosupport of mod-ules.

摘要:

If a finite cyclic group is a direct product of its subsets such that the cardinality of one factor is a product of two primes and the others are of prime cardinalities, then at least one of the factors is a direct product of a subset and a proper subgroup of the group. This settles a 30 years old problem of A. D. Sands,.
