چکیده

We establish an algebraic version of the classical result that a G-map f between G-complexes which restricts to a homotopy equivalence fH on H-fixed sets for all subgroups H of G is a G-homotopy equivalence. This is used to give an alternative proof of a theorem of Bouc. We also include a number of illustrations and applications.

Smith Theory for algebraic varieties

We show how an approach to Smith Theory about group actions on CW–complexes using Bredon cohomology can be adapted to work for algebraic varieties. AMS Classification 57S17; 14F20

A Survey of Anticancer Effect of Some Five- and Six-Membered Palladium (II) Complexes (Containing Bidentate Phosphorus Ligands) on Caco-2 Colon Cancer Cell Line

Background and Objectives: Transition metal complexes possess a variety of biological and pharmacological activities, such as antitumor, antimicrobial, anti-inflammatory, anti-diabetic, and free radical scavenging. Many studies have been carried out on platinum-based chemotherapy agents, however, most attention has been paid to non-platinum metal-based agents in order to find different metal comp...

The category of generalized crossed modules

In the definition of a crossed module $(T,G,rho)$, the actions of the group $T$ and $G$ on themselves are given by conjugation. In this paper, we consider these actions to be arbitrary and thus generalize the concept of ordinary crossed module. Therefore, we get the category ${bf GCM}$, of all generalized crossed modules and generalized crossed module morphisms between them, and investigate som...

Homoclinic Group, Ie Group, and Expansive Algebraic Actions

We give algebraic characterizations for expansiveness of algebraic actions of countable groups. The notion of p-expansiveness is introduced for algebraic actions, and we show that for countable amenable groups, a finitely presented algebraic action is 1-expansive exactly when it has finite entropy. We also study the local entropy theory for actions of countable amenable groups on compact groups...
