Periodic solutions to superlinear indefinite planar systems: a topological degree approach

Guglielmo Feltrin, Juan Carlos Sampedro, Fabio Zanolin

We deal with a planar differential system of the form \begin{equation*} \begin{cases} \, u' = h(t,v), \\ \, v' = - λa(t) g(u), \end{cases} \end{equation*} where is -periodic…

Equilibrium points, periodic solutions and the Brouwer fixed point theorem for convex and non-convex domains

Guglielmo Feltrin, Fabio Zanolin

We show the direct applicability of the Brouwer fixed point theorem for the existence of equilibrium points and periodic solutions for differential systems on general domains satis…
