In this paper.we discuss the a posteriori error estimate of the finite element approximation for the boundary control problems goveed by the parabolic partial d
From a limit model in electric field obtained by letting the frequency vanish in the time-harmonic Maxwell equations, we consider a limit perturbation model in
An optimal control problem goveed by the Stokes equations with L2-norm state constraints is studied.Finite element approximation is constructed.The optimality c
In this paper, we obtain optimal error estimates in both L2-norm and H(curl)-norm for the Nedelec edge finite element approximation of the time-harmonic Maxwell
