Bieri-Eckmann [6] introduced the concept of relative cohomology for a group pair (G, S), where G is a group and S is a family of subgroups of G and, by using that theory, they introduced the concept of Poincaré duality ...

We study conditions on a Banach frame that ensures the validity of a reconstruction formula. In particular, we show that any Banach frames for (a subspace of) Lp or Lp,q (1≤p<∞) with respect to a solid sequence space always ...

© 2016 University of Houston. We introduce covariant structures {(script A, κ), (a, α), (ã, α)} formed of a separable C∗-algebra script A, a measurable twisted action (a, α) of the second-countable locally compact group G ...

We introduce covariant structures {(A, kappa), (a, alpha), ((a) over tilde, (alpha) over tilde)} formed of a separable C*-algebra A, a measurable twisted action (a, alpha) of the second-countable locally compact group G, ...

A  polyhedron in R^n  is a finite union of simplexes in R^n. An MV-algebra is  polyhedral if it is isomorphic to the MV-algebra of all continuous I-valued piecewise linear functions with integer coefficients, defined ...

Este trabalho apresenta um estudo das teorias de cohomologia ordinária de grupos, da cohomologia de Tate e de Farrel, e algumas aplicações no contexto da Topologia Algébrica. Dentro desse contexto foram desenvolvidos, ...
