A condition on the potential for the existence of doubly periodic solutions of a semi-linear fourth-order partial differential equation

We study the existence of solutions to the fourth order semi-linear equation $Delta ^2u=g(u)+h(x)$. We show that there is a positive constant $C_*$, such that if $g(xi )xi geq 0$ for $|xi |geq xi _0$ and $limsup _{|xi |o infty } 2G(xi )/xi^2<C_*$, then for all $hin L^2(Q)$ with $int _Q h dx=0$, t...

description We study the existence of solutions to the fourth order semi-linear equation $Delta ^2u=g(u)+h(x)$. We show that there is a positive constant $C_*$, such that if $g(xi )xi geq 0$ for $|xi |geq xi _0$ and $limsup _{|xi |o infty } 2G(xi )/xi^2<C_*$, then for all $hin L^2(Q)$ with $int _Q h dx=0$, the above equation has a weak solution in $H^2_{2pi}$.
