Under reasonable assumptions, a group action on module extends to the minimal free resolutions of module. Explicit descriptions these actions can lead better understanding by providing, for example, convenient expressions their differentials or alternative characterizations Betti numbers. This article introduces an algorithm computing characters finite groups acting finitely generated graded mo...

Here in this paper, we report the mechanism of the free radical induced oxidation of Resveratrol. Hydroxy cinnamic acid derivatives have been used to examine the effect of molecular structure in antioxidant action. In these molecules addition to several phenolic groups, a vinyl moiety is present in the side chain. This study reveals a direct attestation that the unsaturated functionality in the...

In this paper we give characteristic class formulae for all semicharacteristic classes of all compact, closed manifolds with finite fundamental groups. These invariants are identified with elements in certain odd L-groups, and exactly which elements occur is specified. An appendix calculates the cohomology of the model groups needed. A second appendix determines the structure of the L-groups ne...
