Uniqueness Results for Stokes Equations and Their Consequences in Linear and Nonlinear Control Problems
نویسنده
چکیده
The goal of this article is the study of the approximate controllability for two approximations of Navier Stokes equations with distributed controls The method of proof combines a suitable lin earization of the system with a xed point argument We then are led to study the approximate controllability of linear Stokes systems with potentials We study both the case where there is no constraint on the control and the case where we search a control having one null component In both cases the problems is reduced to prove unique continuation results This is done by means of Carleman estimates

Existence of positive solution to a class of boundary value problems of fractional differential equations
This paper is devoted to the study of establishing sufficient conditions for existence and uniqueness of positive solution to a class of non-linear problems of fractional differential equations. The boundary conditions involved Riemann-Liouville fractional order derivative and integral. Further, the non-linear function $f$ contain fractional order derivative which produce extra complexity. Than...

متن کاملA new block by block method for solving two-dimensional linear and nonlinear Volterra integral equations of the first and second kinds
In this paper, we propose a new method for the numerical solution of two-dimensional linear and nonlinear Volterra integral equations of the first and second kinds, which avoids from using starting values. An existence and uniqueness theorem is proved and convergence isverified by using an appropriate variety of the Gronwall inequality. Application of the method is demonstrated for solving the ...
متن کاملExistence and uniqueness results for a nonlinear differential equations of arbitrary order
This paper studies a fractional boundary value problem of nonlinear differential equations of arbitrary orders. New existence and uniqueness results are established using Banach contraction principle. Other existence results are obtained using Schaefer and Krasnoselskii fixed point theorems. In order to clarify our results, some illustrative examples are also presented.
متن کاملApplication of the linear Differential Equations on the Plane and Elements of Nonlinear Systems, In Economics
In recent years, it has become increasingly important to incorporate explicit dynamics in economic analysis. These two tools that mathematicians have developed, differential equations and optimal control theory, are probably the most basic for economists to analyze dynamic problems. In this paper I will consider the linear differential equations on the plane (phase diagram) and elements of nonl...
