چکیده
In this paper, we deal with the boundary controllability of a one-dimensional degenerate and singular wave equation degeneracy singularity occurring at spatial domain. Exact is proved in range both subcritical critical potentials for sufficiently large time, through controller acting away from degenerate/singular point. By duality argument, reduce problem to an observability estimate corresponding adjoint system, which by means multiplier method new Hardy-type inequalities.

Boundary controllability for the quasilinear wave equation
We study the boundary exact controllability for the quasilinear wave equation in the higher-dimensional case. Our main tool is the geometric analysis. We derive the existence of long time solutions near an equilibrium, prove the locally exact controllability around the equilibrium under some checkable geometrical conditions. We then establish the globally exact controllability in such a way tha...
متن کاملUniform boundary controllability of a discrete 1-D wave equation
A numerical scheme for the controlled discrete 1-D wave equation is considered. We prove the convergence of the boundary controls of the discrete equations to a control of the continuous wave equation when the mesh size tends to zero when time and space steps coincide. This positive result is in contrast with previous negative ones for space semi-discretizations.
متن کاملUnique continuation and approximate controllability for a degenerate parabolic equation
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 vanish on the degeneracy set, together with their conormal derivative, are identically equal to zero. An approximate controllability result for weakly degenerate parabolic equations under Dirichlet boundary c...
متن کاملBlow-up for a degenerate and singular parabolic equation with nonlocal boundary condition
The purpose of this work is to deal with the blow-up behavior of the nonnegative solution to a degenerate and singular parabolic equation with nonlocal boundary condition. The conditions on the existence and non-existence of the global solution are given. Further, under some suitable hypotheses, we discuss the blow-up set and the uniform blow-up profile of the blow-up solution. c ©2016 All righ...
متن کاملExact Controllability for a Semilinear Wave Equation with Both Interior and Boundary Controls
The purpose of this paper is to prove the existence of the exact controllability of a semilinear wave equation with both interior and boundary controls. Let Ω be a bounded open subset of Rn with a smooth boundary, let f (y) be an accretive mapping of L2(0,T ;H−1(Ω)) into L2(0,T ;H 0 (Ω)) with respect to a duality mapping J ,D( f ) = L2(0,T ;L2(Ω)) and having at most a linear growth in y.
