In this paper, the authors study the ω-transience and ω-recurrence for Lévy processes with any weight function ω, give a relation between ω-recurrence
Consider the following Cauchy problem for the first order quasilinear strictly hyperbolic system δu/δt+A(u)δu/δx=0, t=0;u=f(x); We let M=sup x∈R|f''(
<正>This paper deals with the periodic solutions of Schrodinger flow from S3 to S2. It is shown that the periodic solution is related to the variation of some f
The authors study the compressible limit of the nonlinear Schrdinger equation with different-degree small parameter nonlinearities in small time for initial d
Let L be a meet continuous lattice. It is proved that the category Top of topological spaces can be embedded in the category of stratified L-topological spaces
