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…

A Maupertuis-type principle in relativistic mechanics and applications
Alberto Boscaggin, Walter Dambrosio, Eduardo Muñoz-Hernández
We provide a Maupertuis-type principle for the following system of ODE, of interest in special relativity: $$ \frac{\rm d}{{\rm d}t}\left(\frac{m\dot{x}}{\sqrt{1-|\dot{x}|^2/c^2}}\…

Multiplicity of subharmonics in a class of periodic predator-prey Volterra models
Julián López-Gómez, Eduardo Muñoz-Hernández
This paper ascertains the global topological structure of the set of subharmonics of arbitrary order of the periodic predator-prey model introduced in López-Gómez, Ortega and Tineo…
