| Abstract: |
| I will show how a bifurcation approach can be applied to a periodic superlinear boundary value problem also for eigenvalues with even multiplicity. This approach allows us to obtain existence and multiplicity results for local and global branches of periodic solutions with a certain nodal behavior.
The optimality of such results will be also discussed with the aid of numerical simulations.
These results have been obtained in collaboration with Eduardo Mu\~{n}oz-Hern\`{a}ndez (Universidad Complutense de Madrid, Spain) and Juan Carlos Sampedro (Universidad de Cantabria, Spain). |
