Pairs of positive radial solutions for a Minkowski-curvature Neumann problem with indefinite weight
Alberto Boscaggin, Guglielmo Feltrin
We prove the existence of a pair of positive radial solutions for the Neumann boundary value problem \begin{equation*} \begin{cases} \, \mathrm{div}\,\Biggl{(} \dfrac{\nabla u}{\sq…
Multiplicity of clines for systems of indefinite differential equations arising from a multilocus population genetics model
Guglielmo Feltrin, Paolo Gidoni
We investigate sufficient conditions for the presence of coexistence states for different genotypes in a diploid diallelic population with dominance distributed on a heterogeneous…
High multiplicity and chaos for an indefinite problem arising from genetic models
Alberto Boscaggin, Guglielmo Feltrin, Elisa Sovrano
We deal with the periodic boundary value problem associated with the parameter-dependent second-order nonlinear differential equation \begin{equation*} u'' + cu' + \bigr{(} λa^{+}(…
Parabolic orbits in Celestial Mechanics: a functional-analytic approach
Alberto Boscaggin, Walter Dambrosio, Guglielmo Feltrin +1
We prove the existence of half-entire parabolic solutions, asymptotic to a prescribed central configuration, for the equation \begin{equation*} \ddot{x} = \nabla U(x) + \nabla W(t,…
