For any pair n , k of positive integers we produce a strongly Z -graded ring R 2 such that the identity component R has invariant basis number while the 0 integers n, k and n , k having n F n and k Β¬ k we produce a strongly Z -graded 2 Ε½ . ring R such that the basis-number type of R is n, k while t

In this paper all rings R are associative with identity and all R-modules are unital, and the category of all left R-modules will be denoted by R-Mod. If G is a group and R s [ R is a graded ring, we say that R g g g G
We present reduction techniques for studying the category of lattices over strongly graded orders. In particular, we apply these techniques in order to reduce the problem of classifying those strongly graded orders with finite representation type to the case where the coefficient ring is a maximal o
## Abstract In this note we derive a formalism for describing equivariant sheaves over toric varieties. This formalism is a generalization of a correspondence due to Klyachko, which states that equivariant vector bundles on toric varieties are equivalent to certain sets of filtrations of vector spa
We show that the isomorphism ΞΆ B/A B/A β A B introduced by the second author for a subintegral extension A β B of positively graded rings with A 0 = B 0 is also an isomorphism if A β B is only a weakly subintegral extension.
