Variable Exponent Sobolev Spaces for Semilinear Elliptic Systems
(SPRINGER BASEL AG, 2013)In this work, the semilinear elliptic systems with Dirichlet boundary value are considered. We extend the notion of subcritical growth from polynomial growth to variable exponent growth. Under the variable exponent growth, ... 
Vasicek债券定价模型的推广形式
(20060205)V asicek债券定价模型假定即期利率r(t)遵循OU过程,利率的长期均值θ为一个常数.对此进行推广,假设θ遵循一个离散跳跃过程,跳跃的次数与幅度由中央银行根据物价指数确定,建立一个新的模型.运用Ito引理和无套利原理给出到期日价值为1的零息票债券的定价公式. 
VECTORVALUED INEQUALITIES FOR THE COMMUTATORS OF SINGULAR INTEGRALS WITH ROUGH KERNELS
(J KOREAN MATH SOC, 201107)In this paper, we establish the vectorvalued inequalities for the commutators of singular integrals with rough kernels. In particular, our results can essentially improve some wellknown results. 
Vertex operator representations for TKK algebras
(20070215)It is known that, up to isomorphism, there are only one lattice S and one nonlattice semilattice S' in R2. In [S. Tan, TKK algebras and vertex operator representations, J. Algebra 211 (1999) 298342] we obtained a vertex ... 
Vertex operator representations for toroidal Lie algebra of type Bl
(1999)Vertex operator representations for toroidal Lie algebras of simply laced type were studied in [MRY] and [EM]. In this paper we give vertex operator constructions for the toroidal Lie algebra of type Bl (l greater than ... 
Visual tracking via weakly supervised learning from multiple imperfect oracles
(ELSEVIER SCI LTD, 2014 MAR)Notwithstanding many years of progress, visual tracking is still a difficult but important problem. Since most topperforming tracking methods have their strengths and weaknesses and are suited for handling only a certain ... 
wFrchet可微性质和RadonNikod(?)m性质以及wAsplund空间
(20030315)我们称定义在一个Banach空间的对偶空间上的广义实值w*下半连续凸函数f具有w*Frechet可微性质(w*FDP),如果对于该对偶空间上的每个w*下半连续的广义实值凸函数g,只要g≤f,就有g在intdom g的某个稠密的Gδ子集上处处Frechet可微.本文用集合的RadonNikodym性质刻划了该种函数的特征.作为它的一个直接推论,给出了局部化的Collier定理.

Weighted composition followed and proceeded by differentiation operators from Zygmund spaces to Blochtype spaces
(SPRINGER INTERNATIONAL PUBLISHING AG, 20140502)The boundedness and compactness of the weighted composition followed and proceeded by differentiation operators from Zygmund spaces to Blochtype spaces and little Blochtype spaces are characterized. 
Weighted essential nonoscillatory schemes for tidal bore on unstructured meshes
(2009)In this paper, the thirdorder weighted essential nonoscillatory (WENO) schemes are used to simulate the twodimensional shallow water equations with the source terms oil unstructured meshes. The balance of the flux and ...

WENO schemes with LaxWendroff type time discretizations for HamiltonJacobi equations
(2007)In this paper, a class of weighted essentially nonoscillatory (WENO) schemes with a LaxWendroff time discretization procedure, termed WENDLW schemes, for solving HamiltonJacobi equations is presented. This is an ... 
When a digraph and its line digraph are connected and cospectral
