✦ Synopsis
fect or the grading of R is simpler e.g., R is a crossed product or a skew . group ring .
We apply our solution of Problem A to the study of a more concrete problem:
Problem B. Characterize semisimple strongly G-graded rings.

We study G-gradings of the matrix ring M k , k a field, and give a complete n description of the gradings where all the elements e are homogeneous, called i, j good gradings. Among these, we determine the ones that are strong gradings or < < crossed products. If G is a finite cyclic group and k cont
In the present paper we deal with the canonical projection Pic Z Here p is any odd prime number, `pk k =1 and C n is the cyclic group of order p n . I proved in (Stolin, 1997), that the canonical projection Pic Z[`n] Ä Cl Z[`n] can be split. If p is a properly irregular, not regular prime number, t
Let I be an ᒊ-primary ideal in a Buchsbaum local ring A, ᒊ . In this paper, we investigate the Buchsbaum property of the associated graded ring of I when the equality I 2 s ᒎ I holds for some minimal reduction ᒎ of I. However, the Buchsbaum property does not always follow even if I 2 s ᒎ I. So we gi
For any representation of a p-group G on a vector space of dimension 3 over a finite field k of characteristic p, we show how the symmetric algebra, regarded as a kG-module, can be expressed as a direct sum of kG-modules, each one of which is isomorphic to a summand in low degree. It follows that, f
