Ações de Zr2 fixando RPj U CPk
(Universidade Federal de São Carlos, 2017-03-07)
The classification up to equivariant cobordism of smooth involutios (M, T) having fixed set F is a classical problem in cobordism theory. This classification has been studied for several cases of F, of which we highlight ...
Limites singulares para equações do tipo Rosenau-KdV-RLW e Benney-Lin : existência e convergência de soluções
(Universidade Federal de São Carlos, 2017-09-01)
We consider the approximations
@tu + @xf(u) + b1@3xu + b2@t@2xu + 2c@t@4 xu = @2xu (4)
and
@tu + @xf(u) + @2xu + 2b@3 xu + 3c@4xu + 5d@5xu = @2xu (5)
of the Rosenau-KdV-RLW and Benney-Lin equations and ...
Unicidade para equações dos tipos: Burgers, Kuramoto-Sivashinsky e Schrödinger
(Universidade Federal de São Carlos, 2017-12-15)
Based on Carleman's estimates and under certain conditions of linear exponential decay we prove uniqueness for equations of type: Burgers, Kuramoto-Sivashinsky and Schrödinger.
Um estudo qualitativo do contraexemplo de Pinchuk
(Universidade Federal de São Carlos, 2017-02-24)
In this work we studied the topological behaviour of the level curves of the polinomial p
of Pinchuk counterexample of the Real Jacobian Conjecture, namely, a polinomial non
injective map of R^2 with the form (p,q) with ...
Invariantes de germes de aplicações
(Universidade Federal de São Carlos, 2017-04-19)
In this work, we show relations between invariants of map germs. First, we consider an analytic function germ f : (X, 0) —(C, 0) on an isolated determinantal singularity and we present a relation between the Euler obstruction ...
Atratores para processos generalizados e aplicações a um problema não autônomo com dinâmica na fronteira
(Universidade Federal de São Carlos, 2017-03-17)
This work is dedicated to the study of the asymptotic behavior of nonautonomous
evolution problems without uniqueness of solution. More specifically, to the existence
of attractors, in different contexts, for dynamical ...
Solução do problema da conjugação para algumas extensões de grupos
(Universidade Federal de São Carlos, 2017-02-23)
This essay is a detailed introductory study of Combinatorial Group Theory and one of its three classical problems: the Conjugacy Problem. We studied its solution for several classes of group extensions, obtained in [1] and ...
Imersões de variedades de Dold e de Wall em espaços euclidianos
(Universidade Federal de São Carlos, 2017-03-10)
Relative differential cohomology
(Universidade Federal de 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 ...
Identidades polinomiais via identidades de grupo : a conjectura de Brian Hartley
(Universidade Federal de São Carlos, 2017-02-16)
In this work, we present the Conjecture of Brian Hartley and study its validity, i.e, we verify
if group identities in the unity group U(FG) make FG satisfy a polynomial identity, where G
is a torsion group and F any ...
