Arithmetic fuchsian groups and space time block codes
(Computational & Applied Mathematics, 2011-01-01) [Artigo]
In the context of space time block codes (STBCs) the theory of arithmetic Fuchsian groups is presented. Additionally, in this work we present a new class of STBCs based on arithmetic Fuchsian groups. This new class of codes ...
THREE TIME SCALE SINGULAR PERTURBATION PROBLEMS AND NONSMOOTH DYNAMICAL SYSTEMS
(Quarterly Of Applied Mathematics, 2014-01-01) [Artigo]
In this paper we study three time scale singular perturbation problemsepsilon x ' = f(x, epsilon, delta), y ' = g(x, epsilon, delta), z ' = delta h(x, delta, delta),where x = (x, y, z) is an element of R-n x R-m x R-p, ...
Filippov's selection theorem and the existence of solutions for optimal control problems in time scales
(Computational & Applied Mathematics, 2014-04-01) [Artigo]
We obtain an extension of Filippov's Lemma to control systems in time scales, where the multifunction associated with the dynamics is delta measurable on time and Lipschitz on the state variable. Using a modified version ...
