摘要：
This work focuses on higher-dimensional quasi-periodically forced nonlinear beam equation. This means studying u(tt) + (-Delta + M xi)(2)u + e phi(t)(u + u(3)) = 0, x is an element of R-d, t is an element of R with periodic boundary conditions, where epsilon is a small positive parameter, phi(t) is a real analytic quasi-periodic function in t with frequency vector omega = (omega(1),omega(2),...,omega(m)). It is proved that there are many quasi-periodic solutions for the above equation via KAM theory.
