In this paper,we obtain some normality criteria for families of meromorphic functions concering shared values,which extends the related results of Schwick,and SauerSchweizer,and can be viewed as a complement of the re...

The decay estimations of the solution to an elliptic equation with dynamical boundary condition is considered.We proved that,for suitable initial datum,the energy of the solution decays "in time" exponentially if p=0,...
There have been a great many of studies on the pointed representations of fi- nite-dimensional sanple Lie algebras.cf.[1][2]etc.In this paper we give a new proof of an impottant Lemma,and from this we derive our main ...
The main result of this paper is as follows. Let n_o ∈ Z^+ be a period of the covering function σ (x)= 1. If d∈Z^+ divides some n_(l≤i≤k) and d|u_o,then the number of the n_i divided by d is at least d/(d,n.)wher...
The follwing theorem has been proved by Clunie. If f(z) is a transcendental integral function,then f'(z)f(z) assumes all values except possibly zero infinitely often. In this paper we improve the above theorem,and pro...
