Ordinary and twisted K-theory
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Matemática - PPGMCâmpus São Carlos, 2022-03-28)
The main topic of this thesis consists in Ordinary and Twisted Topological K-Theory. We begin by describing generalized cohomology theories through the Eilenberg-Steenrod Axioms, in order to set Ordinary K-Theory in these ...
On the K-theory of Z-categories
(arXiv, 2022)
We relate the notions of Noetherian, regular coherent and regular n-coherent category for Z-linear categories with finite objects with the corresponding notions for unital rings. We use this relation to obtain a vanishing ...
Relative differential cohomology
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Matemática - PPGMCâmpus São Carlos, 2017-09-27)
We briefly review the classical construction of the Cheeger-Simons characters, the Deligne cohomology groups and the differential K-theory groups, which are representatives of the absolute differential refinement of the ...
L'interpretation de la classe de Maslov dans la K-theorie Hermitienne et dans la theorie relative de Chern-Weil
(1998)
The purpose of this paper is, first to define the Maslov invariant in the U-theory, the intermediate theory between real K-theory and complex K-theory, whose vanishing is a necessary and sufficient condition for the stable ...
Cálculo K: uma abordagem alternativa para a relatividade especial
(Soc Brasileira Fisica, 2013-12-01)
In this paper we present an alternative approach due to Bondi for the special theory of relativity. During the development, we analyse the Bondi diagrams, visual resources from which we can take some information about the ...
The transformation between exploration and exploitation applied to inventors of packaging innovations
(Elsevier B.V., 2010-05-01)
While the inventor is often the driver of an invention in the early stages, he/she needs to move between different social networks for knowledge in order to create and capture value. The main objective of this research is ...

Algebraic kk-theory and the KH-isomorphism conjecture
(arXiv, 2022)
We relate the Davis-Lück homology with coefficients in Weibel's homotopy K-theory to the equivariant algebraic kk-theory using homotopy theory and adjointness theorems. We express the left hand side of the assembly map for ...
On the algebraic K theory of the massive D8 and M9-branes
(World Scientific Publ Co Pte Ltd, 2001-10-30)
In this paper we review some basic relations of algebraic K theory and we formulate them in the language of D-branes. Then we study the relation between the D8-branes wrapped on an orientable, compact manifold W in a massive ...
