Abstract
We consider degenerate parabolic equations of the form
in a bounded domain \({\Omega\subset\mathbb{R}^N}\), where Δλ is a subelliptic operator of the type
We prove global existence of solutions and characterize their longtime behavior. In particular, we show the existence and finite fractal dimension of the global attractor of the generated semigroup and the convergence of solutions to an equilibrium solution when time tends to infinity.
