Abstract

In this paper, we put forward the concept of polynomial attractor and study the connection between the polynomial attractors and the estimate of attractive velocity of bounded sets for infinite-dimensional dynamical systems. Then we prove the existence of polynomial attractor for a class of extensible beams with nonlocal weak damping for the case that the nonlinear term $f$ has subcritical growth.
