Our aim in this paper is to study the long-time behavior for a class of doubly nonlinear parabolic equations. First we show that the problem has a unique solution. Then we prove that the semigroup corresponding to the problem is norm-to-weak continuous in 𝐿𝑞 and 𝐻10. Finally we establish the existence of global attractor of the problem in 𝐿𝑞 and 𝐻10.
