Periodic solutions for evolution equations
Mihaï Bostan · Electronic Journal of Differential Equations · 2002
We study the existence and uniqueness of periodic solutions for evolution equations. First we analyze the one-dimensional case. Then for arbitrary dimensions (finite or not), we consider linear symmetric operators. We also prove the same results for non-linear sub-differential operators \(A = \partial \varphi\) where \(\varphi\) is convex.
