Global multiplicity results in a Moore-Nehari type problem with a spectral parameter
Julián López-Gómez, Eduardo Muñoz-Hernández, Fabio Zanolin
This paper analyzes the structure of the set of positive solutions of a Moore-Nehari type problem, where is a piece-wise constant function defined for some $h\in (0,1…

Bifurcation Theory for a Class of Periodic Superlinear Problems
Eduardo Muñoz-Hernández, Juan Carlos Sampedro, Andrea Tellini
We analyze, mainly using bifurcation methods, an elliptic superlinear problem in one-dimension with periodic boundary conditions. One of the main novelties is that we follow for th…

Coupled reaction-diffusion equations with degenerate diffusivity: wavefront analysis
Eduardo Muñoz-Hernández, Elisa Sovrano, Valentina Taddei
We investigate traveling wave solutions for a nonlinear system of two coupled reaction-diffusion equations characterized by double degenerate diffusivity: \[n_t= -f(n,b), \quad b_t…
