Abstract: In this paper, we are concerned with the existence of invariant tori in nearly integrable Hamiltonian systems $$\begin{aligned} H=h(y)+f(x,y,t), \end{aligned}$$H=h(y)+f(x,y,t),where $$y\in D\subseteq \mathbb {R}^n$$y∈D⊆Rn with D being an open bounded domain, $$x\in \mathbb {T}^n$$x∈Tn, f(x, y, t)… read more here.
