Unique continuation and approximate controllability for a degenerate parabolic equation
degenerate parabolic equations unique continuation approximate controllability local Carleman estimate
2011/9/13
Abstract: This paper studies unique continuation for weakly degenerate parabolic equations in one space dimension. A new Carleman estimate of local type is obtained to deduce that all solutions that v...
Finite-dimensional approximate controllability for a nonlocal parabolic problem
Approximate Controllability Diffusion Equation Optimal Control
2010/9/13
In this work we investigate finite–approximate controllability for a nonlocal parabolic problem defined in an bounded domain of RN. First, using a variational approach, we prove the controllability re...
APPROXIMATE CONTROLLABILITY OF NONAUTONOMOUS PAST DELAY EQUATIONS
Partial differential equations with delay semigroup resolvent approximate controllability population equation

In this paper, we study the approximate controllability of partial differential equations with
nonautonomous past delay in Lp -phase spaces. We illustrate our abstract results by the approximate
