BOUNDARY LAYER ASYMPTOTIC BEHAVIOR OF INCOMPRESSIBLE NAVIER-STOKES EQUATION IN A CYLINDER WITH SMALL VISCOSITY 段志文; 韩淑霞; 周笠 数学物理学报(英文版). 2008 (3):  449-468.  DOI: 10.1016/S0252-9602(08)60047-8 摘要 ( 1396 )   RICH HTML PDF(236KB) ( 1665 )   收藏 The object of this article is to study the boundary layer appearing at large Reynolds number (small viscosity ε) incompressible Navier-Stokes Equation in a cylinder in space dimension three. These are Navier-Stokes equations linearized around a fixed velocity flow: the authors study the convergence as ε→ 0 to the inviscid type equations, the authors define the correctors needed to resolve the boundary layer and obtain convergence results valid up to the boundary and the authors also study the behavior of the boundary layer when, simultaneously, time and the Reynolds number tend to infinity, in which case the boundary layer tends to pervade the whole domain. 相关文章 | 计量指标

HARDY-SOBOLEV INEQUALITIES WITH GENERAL WEIGHTS AND REMAINDER TERMS 陈志辉; 沈尧天 数学物理学报(英文版). 2008 (3):  469-478.  DOI: 10.1016/S0252-9602(08)60048-X 摘要 ( 1214 )   RICH HTML PDF(179KB) ( 1567 )   收藏 The Hardy-Sobolev inequality with general weights is established, and it is shown that the constant is optimal. The two weights in this inequality are determined by a Bernoulli equation. In addition, the authors obtain the Hardy-Sobolev inequality with general weights and remainder terms. By choosing special weights, it turns to be many versions of the Hardy-Sobolev inequality and the Caffarelli-Kohn-Nirenberg inequality with remainder terms in the literature. 相关文章 | 计量指标

STEADY-STATE SOLUTIONS FOR A ONE-DIMENSIONAL NONISENTROPIC #br# HYDRODYNAMIC MODEL WITH NON-CONSTANT LATTICE TEMPERATURE 黎野平 数学物理学报(英文版). 2008 (3):  479-488.  DOI: 10.1016/S0252-9602(08)60049-1 摘要 ( 1118 )   RICH HTML PDF(156KB) ( 1261 )   收藏 A one-dimensional stationary nonisentropic hydrodynamic model for semiconductor devices with non-constant lattice temperature is studied. This model consists of the equations for the electron density, the electron current density and electron temperature, coupled with the Poisson equation of the electrostatic potential in a bounded interval supplemented with proper boundary conditions. The existence and uniqueness of a strong subsonic steady-state solution with positive particle density and positive temperature is established. The proof is based on the fixed-point arguments, the Stampacchia truncation methods, and the basic energy estimates. 相关文章 | 计量指标

This algorithm does not require the feasibility of the initial points and iteration points. Under suitable assumptions, it is shown that the algorithm can find an ε-approximate solution of an SOCP in at most O(\sqrt{n}\ln(ε0/ε)) iterations. The iteration-complexity bound of our algorithm is almost the same as the best known bound of feasible interior point algorithms for the SOCP. 相关文章 | 计量指标

TESTING OF CORRELATION AND HETEROSCEDASTICITY IN NONLINEAR REGRESSION MODELS WITH DBL(p,q,1) RANDOM ERRORS 刘应安; 韦博成 数学物理学报(英文版). 2008 (3):  613-632.  DOI: 10.1016/S0252-9602(08)60064-8 摘要 ( 1151 )   RICH HTML PDF(218KB) ( 1361 )   收藏 Chaos theory has taught us that a system which has both nonlinearity and random input will most likely produce irregular data. If random errors are irregular data, then random error process will raise nonlinearity (Kantz and Schreiber (1997)). Tsai (1986) introduced a composite test for autocorrelation and heteroscedasticity in linear models with AR(1) errors. Liu (2003) introduced a composite test for correlation and heteroscedasticity in nonlinear models with DBL(p,0,1) errors. Therefore, the important problems in regression model are detections of bilinearity, correlation and heteroscedasticity. In this article, the authors discuss more general case of nonlinear models with DBL(p,q,1) random errors by score test. Several statistics for the test of bilinearity, correlation, and heteroscedasticity are obtained, and expressed in simple matrix formulas. The results of regression models with linear errors are extended to those with bilinear errors. The simulation study is carried out to investigate the powers of the test statistics. All results of this article extend and develop results of Tsai (1986), Wei, et al (1995), and Liu, et al (2003). 相关文章 | 计量指标

NEGATIVE NORM LEAST-SQUARES METHODS FOR THE INCOMPRESSIBLE MAGNETOHYDRODYNAMIC EQUATIONS 高少芹; 段火元 数学物理学报(英文版). 2008 (3):  675-684.  DOI: 10.1016/S0252-9602(08)60069-7 摘要 ( 1168 )   RICH HTML PDF(158KB) ( 1517 )   收藏 The purpose of this article is to develop and analyze least-squares approximations for the incompressible magnetohydrodynamic equations. The major advantage of the least-squares finite element method is that it is not subjected to the so-called Ladyzhenskaya-Babuska-Brezzi (LBB) condition. The authors employ least-squares functionals which involve a discrete inner product which is related to the inner product in H-1(\Omega). 相关文章 | 计量指标

A NEW SELF-ADAPTIVE ITERATIVE METHOD FOR GENERAL MIXED QUASI #br# VARIATIONAL INEQUALITIES Abdellah Bnouhachem; Mohamed Khalfaoui; Hafida Benazza 数学物理学报(英文版). 2008 (3):  685-696.  DOI: 10.1016/S0252-9602(08)60070-3 摘要 ( 1097 )   RICH HTML PDF(180KB) ( 1163 )   收藏 The general mixed quasi variational inequality containing a nonlinear term ψ is a useful and an important generalization of variational inequalities. The projection method can not be applied to solve this problem due to the presence of nonlinear term. It is well known that the variational inequalities involving the nonlinear term ψ are equivalent to the fixed point problems and resolvent equations. In this article, the authors use these alternative equivalent formulations to suggest and analyze a new self-adaptive iterative method for solving general mixed quasi variational inequalities. Global convergence of the new method is proved. An example is given to illustrate the efficiency of the proposed method. 相关文章 | 计量指标

TIME INCONSISTENCY AND REPUTATION IN MONETARY POLICY: A STRATEGIC#br# MODELLING IN CONTINUOUS TIME 李静远; 田国强 数学物理学报(英文版). 2008 (3):  697-710.  DOI: 10.1016/S0252-9602(08)60071-5 摘要 ( 1186 )   RICH HTML PDF(197KB) ( 1110 )   收藏 This article develops a model to examine the equilibrium behavior of the time inconsistency problem in a continuous time economy with stochastic and endogenized distortion. First, the authors introduce the notion of sequentially rational equilibrium, and show that the time inconsistency problem may be solved with trigger reputation strategies for stochastic setting. The conditions for the existence of sequentially rational equilibrium are provided. Then, the concept of sequentially rational stochastically stable equilibrium is introduced. The authors compare the relative stability between the cooperative behavior and uncooperative behavior, and show that the cooperative equilibrium in this monetary policy game is a sequentially rational stochastically stable equilibrium and the uncooperative equilibrium is sequentially rational stochastically unstable equilibrium. In the long run, the zero inflation monetary policies are inherently more stable than the discretion rules, and once established, they tend to persist for longer periods of the time. 相关文章 | 计量指标

THE EXTENSION OPERATOR IN BANACH SPACES FOR LOCALLY BIHOLOMORPHIC MAPPINGS 刘名生; 朱玉灿 数学物理学报(英文版). 2008 (3):  711-720.  DOI: 10.1016/S0252-9602(08)60072-7 摘要 ( 1041 )   RICH HTML PDF(172KB) ( 1446 )   收藏 In this article, the generalized Roper--Suffridge extension operator in Banach spaces for locally biholomorphic mappings is introduced. It is proved that this operator preserves the starlikeness on some domains in Banach spaces but does not preserves convexity for some cases. Moreover, the growth theorem, covering theorem, and the radius of starlikeness are discussed. Some results of Roper and Suffridge, Gong and Liu, Graham et al in <b> C</b>n are extended to Hilbert spaces or Banach spaces. 相关文章 | 计量指标
