Existence and multiplicity results for degenerate elliptic equations with dependence on the gradient
(2007)
We study the existence of positive solutions for a class of degenerate nonlinear elliptic equations with gradient dependence. For this purpose, we combine a blowup argument, the strong maximum principle, and Liouville-type ...
Existence and multiplicity of periodic solutions for a generalized hematopoiesis model
(Springer Verlag Berlín, 2017-10)
A generalization of the nonautonomous Mackey–Glass equation for the regulation of the hematopoiesis with several non-constant delays is studied. Using topological degree methods we prove, under appropriate conditions, the ...
Positive solutions of the p-Laplacian involving a superlinear nonlinearity with zeros
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2010)
Using a combination of several methods, such as variational methods. the sub and supersolutions method, comparison principles and a priori estimates. we study existence, multiplicity, and the behavior with respect to lambda ...
