A robust multiplicity result in a generalized diffusive predator-prey model
Julián López-Gómez, Eduardo Muñoz-Hernández
This paper analyzes the generalized spatially heterogeneous diffusive predator-prey model introduced by the authors in \cite{LGMH20}, whose interaction terms depend on a saturation…
Subharmonic solutions for a class of predator-prey models with degenerate weights in periodic environments
Julián López-Gómez, Eduardo Muñoz-Hernández, Fabio Zanolin
This paper deals with the existence, multiplicity, minimal complexity and global structure of the subharmonic solutions to a class of planar Hamiltonian systems with periodic coeff…
Generating loops and isolas in semilinear elliptic BVP's
Julián López-Gómez, Juan Carlos Sampedro
In this paper, we ascertain the global -structure of the set of positive and negative solutions bifurcating from for the semilinear elliptic BVP \begin{equation*} \left\{\…
Rich dynamics in planar systems with heterogeneous nonnegative weights
Julián López-Gómez, Eduardo Muñoz-Hernández, Fabio Zanolin
This paper studies the global structure of the set of nodal solutions of a generalized Sturm--Liouville boundary value problem associated to the quasilinear equation $$ -(ϕ(u'))'=…
