Range of semilinear operators for systems at resonance
For a vector function $u:mathbb{R} o mathbb{R}^N $ we consider the system $$displaylines{ u''(t)+ abla G(u(t))= p(t)cr u(t)=u(t+T), }$$ where $G: mathbb{R}^N o mathbb{R}$ is a $C^1$ function. We are interested in finding all possible T-periodic forcing terms p(t) for which there is...
