The Ambrosetti-Prodi periodic problem: Different routes to complex dynamics
Elisa Sovrano, Fabio Zanolin
We consider a second order nonlinear ordinary differential equation of the form where the forcing term is a -periodic function and the nonlinearity $f…

Three positive solutions to an indefinite Neumann problem: a shooting method
Guglielmo Feltrin, Elisa Sovrano
We deal with the Neumann boundary value problem \begin{equation*} \begin{cases} \, u" + \bigl{(} λa^{+}(t)-μa^{-}(t) \bigr{)}g(u) = 0, \\ \, 0 < u(t) < 1, \quad \forall\, t\in\math…

A negative answer to a conjecture arising in the study of selection-migration models in population genetics
Elisa Sovrano
We deal with the study of the evolution of the allelic frequencies, at a single locus, for a population distributed continuously over a bounded habitat. We consider evolution which…
