1. Actions of groups on sphere product, cohomology of virtually cyclic groups (ZaX| Zb)X| Z and [ZaX|(ZbXQ2i)]X|Z and Tate Cohomology / Ações de p-grupos sobre produto de esferas, co-homologia dos grupos virtualmente cíclicos (Z IND.aX| Z IND. b)X| Z e [Z IND.aX| (Z IND.bX Q IND.2 POT. i)] X| Z e cohomologia de Tate
In this work is studied the rank of the fixed point set of a semifree action on spaces X~p S POT.nX S POT.nand X~p S POT.nX S POT.nX S POT.n, with n>0. We also consider the extension of the result for actions of p-groups on spaces X~p SPOT.nX S POT.m, with 0

2. High dimensional cohomology of discrete groups
For a large class of discrete groups Γ, relations are established between the high dimensional cohomology of Γ and the cohomology of the normalizers of the finite subgroups of Γ. The results are stated in terms of a generalization of Tate cohomology recently constructed by F. T. Farrell. As an illustration of these results, it is shown that one can recove

3. Integrality of Tate-cycles
We explain a technical result about p-adic cohomology and apply it to the study of Shimura varieties. The technical result applies to algebraic varieties with torsion-free cohomology, but for simplicity we only treat abelian varieties.
