Neuronal dynamics in time varying enviroments: Continuous and discrete time models
A topological degree approach to sublinear systems of second order differential equations
| 1. | Dipartimento di Matematica, Università di Torino, Via Carlo Alberto 10, 10123 Torino, Italy, Italy |
We first give a multiplicity result on solutions with prescribed nodal properties; then, we show the existence of positive solutions. The proofs are based on topological degree arguments.
