Abstract: In this talk, we give some existence results of degenerate invariant tori in quasi-periodically forced skew-product maps. In one-dimensional case, we give the relation among perturbation, non-resonant condition and the order of main term to produce invariant tori. In two-dimensional case, we give the coexistence of hyperbolic tori and elliptic tori. And the numbers of invariant tori are also considered in our work.
