Streamline topologies in Stokes flow within lid-driven cavities
收藏 引用
THEORETICAL AND COMPUTATIONAL FLUID DYNAMICS 2003年 第1期17卷 19-30页
作者: Gürcan, F Erciyes Univ Dept Math TR-38039 Kayseri Turkey
Stokes flow in a rectangular cavity with two moving lids (with equal speed but in opposite directions) and aspect ratio A (height to width) is considered. An analytic solution for the stream function, psi, expressed a... 详细信息

Inverse problem on the half-line for the Sturm-Liouville operator with periodic potential
收藏 引用
DIFFERENTIAL EQUATIONS 2015年 第1期51卷 23-32页
作者: Khasanov, A. B. Yakhshimuratov, A. B. Urgench State Univ Urgench Uzbekistan
We study the inverse spectral problem on the half-line for the Sturm-Liouville operator with periodic potential. We derive a formula expressing the boundary condition via the spectral data and an analog of Dubrovin... 详细信息

Asymptotics of the spectrum of the Sturm-Liouville operator with regular boundary conditions
收藏 引用
DIFFERENTIAL EQUATIONS 2008年 第5期44卷 645-658页
作者: Makin, A. S. Moscow State Univ Mech Engn & Comp Sci Moscow Russia
On the interval (0, pi), we consider the spectral problem generated by the Sturm-Liouville operator with regular but not strongly regular boundary conditions. For an arbitrary potential q(x) is an element of L(1) (0, ... 详细信息

Solution to classes of inverse coefficient problems and problems with nonlocal conditions for parabolic equations
收藏 引用
DIFFERENTIAL EQUATIONS 2015年 第1期51卷 83-93页
作者: Aida-zade, K. R. Rahimov, A. B. Azerbaijan State Oil Acad Baku Azerbaijan Azerbaijan Natl Acad Sci Inst Control Syst Baku Azerbaijan
We study the numerical solution to inverse problems in which one reconstructs the coefficients of a parabolic equation depending only on one (space or time) variable. In particular, these classes of problems arise in ... 详细信息

ANOTHER NOTE ON THE JOIN PROPERTY
收藏 引用
PROCEEDINGS OF THE AMERICAN MATHEMATICAL SOCIETY 2015年 第9期143卷 4059-4072页
作者: Cai, Mingzhong Univ Wisconsin Dept Math Madison WI 53706 USA
We first prove two theorems on the low(2) degrees and the join property in the local structure D(<= 0'): An r.e. degree is low(2) if and only if it is bounded by an r.e. degree without the join property (in D(&... 详细信息

Optimal resource allocation program in a two-sector economic model with a Cobb-Douglas production function
收藏 引用
DIFFERENTIAL EQUATIONS 2010年 第12期46卷 1750-1766页
作者: Kiselev, Yu N. Orlov, M. V. Moscow MV Lomonosov State Univ Moscow Russia
We consider the resource allocation problem for a two-sector economic model with a two-factor Cobb-Douglas production function on a finite time horizon with a terminal functional. The problem is reduced to some canoni... 详细信息
