Existence theorems for some abstract nonlinear non-autonomous systems with delays
(Elsevier Science, 2014-09)
For some abstract classes of nonlinear non-autonomous systems with variable and state-dependent delays existence, non-existence and multiplicity of periodic solutions are discussed. To illustrate the efficiency of the ...
Periodic solutions for indefinite singular equations with singularities in the spatial variable and non-monotone nonlinearity
(American Institute of Mathematical Sciences, 2018-10)
TWe prove the existence of T−periodic solutions for the second order non-linear equation u0 1 − u02 0 = h(t)g(u), where the non-linear term g has two singularities and the weight function h changes sign. We find a relation ...
Existência de soluções para um problema do tipo (p; q)-Laplaciano com perturbação
(Universidade Federal de Santa MariaBrasilMatemáticaUFSMPrograma de Pós-Graduação em MatemáticaCentro de Ciências Naturais e Exatas, 2015-08-10)
In this paper, considering _ RN (N > 2) a bounded smooth domain, using blow-up
techniques and the Leray Schauder Topological Degree theory, we intend to ensure the
existence of positive solutions for a problem involving ...

Soluciones periódicas para reacciones bioquímicas catalizadas con enzimas
(Universidad Michoacana de San Nicolás de Hidalgo, 2019-03)
Mathematical models have been become important tools in the analysis of chemical reactions, enzymatic reactions in biochemical systems are of special interest. A basic scheme for an enzyme catalyzed reaction is based on ...
