Floquet topological transitions in a driven one-dimensional topological insulator
(American Physical Society, 2015-08)
The Su-Schrieffer-Heeger model of polyacetylene is a paradigmatic Hamiltonian exhibiting nontrivial edge states. By using Floquet theory we study how the spectrum of this one-dimensional topological insulator is affected ...
CONNECTEDNESS IN JÄGER - ŠOSTAK'S I-FUZZY TOPOLOGICAL SPACES
(Universidad Católica del Norte, Departamento de Matemáticas, 2009)
A homological version of the implicit function theorem
Problemas elípticos superlineares com não linearidades assimétricas
(Universidade Federal de São CarlosUFSCarPrograma de Pós-graduação em MatemáticaCâmpus São Carlos, 2015-03-06)
The aim of this work is to present results of existence of solutions for a class of nonlinear asymmetryc elliptic problems. The asymmetry that we consider here has linear behavior on - infnity and superlinear on + infnity. ...

On the detection of several obstacles in 2d stokes flow: topological sensitivity and combination with shape derivatives
(Amer Inst Mathematical Sciences-AIMS, 2016)
We consider the inverse problem of detecting the location and the shape of several obstacles immersed in a uid owing in a larger bounded domain from partial boundary measurements in the two dimensional case. The ...

QUASI-TOPOLOGICAL QUANTUM FIELD THEORIES AND Z(2) LATTICE GAUGE THEORIES
(WORLD SCIENTIFIC PUBL CO PTE LTDSINGAPORE, 2012)
We consider a two-parameter family of Z(2) gauge theories on a lattice discretization T(M) of a three-manifold M and its relation to topological field theories. Familiar models such as the spin-gauge model are curves on a ...
A topological equivalence result for a family of nonlinear difference systems having generalized exponential dichotomy
(Taylor & Francis, 2016)
We obtain sufficient conditions ensuring the topological and strong topological equivalence of two perturbed difference systems whose linear part has a property of generalized exponential dichotomy. When the exponential ...
A group topology on the free abelian group of cardinality c that makes its square countably compact
(POLISH ACAD SCIENCES INST MATHEMATICS, 2011)
Under p = c, we prove that it is possible to endow the free abelian group of cardinality c with a group topology that makes its square countably compact. This answers a question posed by Madariaga-Garcia and Tomita and by ...
