Periodic solutions to parameter-dependent equations with a $\varphi$-Laplacian type operator

Guglielmo Feltrin, Elisa Sovrano, Fabio Zanolin

We study the periodic boundary value problem associated with the $\varphi$-Laplacian equation of the form $(\varphi (u^{\prime }){)}^{\prime }+f(u)u^{\prime }+g(t,u)=s$, where $s$ is a real parameter, $f$ and $g$ are conti…
