In this paper we introduce a method to construct periodic solutions for the n-body problem with only boundary and topological constraints.Our approach is based
In this paper,we give a survey on the Hill-type formula and its applications.Moreover,we generalize the Hill-type formula for linear Hamiltonian systems and Stu

We study the insulated conductivity problem with inclusions embedded in a bounded domain in Rn.When the distance of inclusions,denoted by ε,goes to 0,the gradi
