Existence and smoothness of solutions to second initial boundary value problems for Schrodinger systems in cylinders with non-smooth bases

Electronic Journal of Differential Equations, 2008
In this paper, we consider the second initial boundary value problem for strongly general Schrodinger systems in both the finite and the infinite cylinders $Q_T ...

The Influence of Non-Isothermal Conditions on Pressure Head Jumps in the Nonlinear Consolidation Problem in the Presence of Geobarriers

Journal of Optimization, Differential Equations and Their Applications
A nonlinear boundary value problem is considered for a system of parabolic equations in an inhomogeneous region, that requires conjugation conditions.

Existence of weak solutions for mixed problems of parabolic systems

Electronic Journal of Differential Equations, 2010
The purpose of this paper is to investigate the existence of generalized solutions for strongly parabolic systems in a cylindrical domain. The decay of the solution at infinity, depending on the right-hand of the equation, is also studied in this ...

MULTITEMPORAL GENERALIZATION OF THE SCHWARZSCHILD SOLUTION [PDF]

International Journal of Modern Physics D, 1995
The n-time generalization of the Schwarzschild solution is considered. The equations of geodesics for the metric are integrated. The multitemporal analogues of Newton’s laws for the extended objects described by the solution are suggested. The scalar-vacuum generalization of the solution is also presented.

Solvability of a nonlocal problem for a hyperbolic equation with degenerate integral conditions

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2019
In this paper, we consider a nonlocal problem with integral conditions for hyperbolic equation. Close attention focuses on degenerate integral conditions, namely, on the second kind integral conditions which degenerate into the first kind conditions at ...

Generalized analytical solution for advection-dispersion equation in finite spatial domain with arbitrary time-dependent inlet boundary condition [PDF]

Hydrology and Earth System Sciences, 2011
This study presents a generalized analytical solution for one-dimensional solute transport in finite spatial domain subject to arbitrary time-dependent inlet boundary condition. The governing equation includes terms accounting for advection, hydrodynamic

A problem with nonlocal integral 1st kind conditions for 4th order partial differential equation

Вестник Самарского университета: Естественнонаучная серия
In this article, we consider a nonlocal problem with integral conditions for one-dimensional 4th order partial differential equation. A distinguishing feature of this problem is the presence of integral conditions of the 1st kind.

A Generic Solution?

Current Anthropology, 2007
In 1997 and 1998 the Mexican government encouraged the introduction of generic drugs into Mexico, Latin America’s biggest and fastest-growing pharmaceutical market. In contrast to the situation in Brazil, where anti-retrovirals and HIV/AIDS treatment have been the centerpiece of a powerful stateled generics “revolution,” in Mexico the move to cheaper ...
