Two properties are given in this paper about the scaling Vj;j∈Z is a multiresolution analysis with a continuous scaling function φ which have compact support
In this paper, we consider the regularity of solution in S for Zakharov-Kuznestov equation in H^s(s>2). Meanwhile, by method of undetermined coefficient we prov
In this paper,we discuss the positive definite problem of a binary quartic form and obtain a necessary and sufficient condition .In addition we give two example
