摘要:

In this paper the reader is assumed to have taken notice of [I]. In [III] 1 we described the $lambda;, and s-, structure of the Green ring of GL(2,Fp), and Sl(2,Fp). We shall now construct a subring of the Green ring which is invariant for the $lambda;, and s-, operations. It is generated by all the indecomposables with odd-dimensional composition factors. This sheds another light on the results in the previous sections. We shall also study a certain quotient of the Green ring, which is in fact the Green ring of a certain subgroup of GL(2,Fp) consisting of upper triangular matrices. The multiplication and the λ, s-, structure of this quotient Green ring is described. Moreover it is shown how this λ and s-, structure controls the deviation from being a λ, respectively s-, ring of the Green ring of any finite group with a normal Sylow subgroup of order p. The sequence of Adams operations for these groups is shown to be periodic, and the period reflects the internal p-structure of these groups.

摘要:

We give an example of an order, over the integers, whose lattices satisfy the Krull—Schmidt theorem but whose finitely generated modules do not satisfy direct—sum cancellation

摘要:

We prove thata locally trivial Lie algebra bundle is a semidirect product of its radical bundle and a semisimple bundle by using thecohomological methods.A simple bundle which is not semisimple is given and it is also an example of a non locally trivial bundle for which such a decomposition fails.
