In this paper, a new set of sufficient conditions related to an initial value problem and global homeomorphism is obtained in discussing the existence and uniqueness of 2π-periodic solution for 2kth order differentia...
In this paper,we consider the following systems x″+ Bx′+ gradG(x,t) = 0.Weak sufficient condition for the existence of a unique 2π-periodic solution of the systems is given and the results in [1]~ [3],[7]~ [8]are c...
In this paper the homeomorphism number of G. M.has been finded with the method of that push the negative edges in inner tier and outer tier into the middle tier as far as possible.
The Beurling-Ahlfors’ extension is studied under relatively general conditions and its dilatation fonction is estimated. Particularly, the classic Deurling -Ahlfors’ theorem can be obtained under the M-condition.
In this paper,we introduced the concept of (E_1) topology in Banach space, and gave the equivalent condition between (E_1) topology and norm topology. With the concept of (E_1) topology, the linear homeomorphism of a ...
