In this paper, we use KAM methods to prove that there are positive measure Cantor sets such that for small perturbation parameters in these Cantor sets a class of almost periodic linear differential equations are redu...

In the present paper, we consider a class of compact orientable 3-manifolds with one boundary component, and suppose that the manifolds are ?-reducible and admit complete surface systems. One of our main results says ...

In this paper, the Dirichlet boundary value problems of the nonlinear beam equation utt + △^2u + αu + εφ(t)(u + u^3) = 0 , α 〉 0 in the dimension one is considered, where u(t,x) and φ(t...
We consider a central hyperplane arrangement in a three-dimensional vector space. The definition of characteristic form to a hyperplane arrangement is given and we could make use of characteristic form to judge the re...
