Weak solvability of a hyperbolic integro-differential equation with integral condition
By using the method of semidiscretization in time also called the Rothe's method, we prove the existence, uniqueness of the weak solution and its continuous dependence upon data, for an hyperbolic integro-differential equation with initial, Neumann and ...

An Error Indicator for Semidiscrete Schemes [PDF]
The eectiv eness of adaptive mesh renemen t strategies (AMR) relies heavily on the quality of the indicator that drives the process of mesh renemen t and coarsening. In this work, an indicator based on the local production of entropy is proposed, extending previous work by the authors on one-dimensional schemes, based on staggered cells.

Stability under Galerkin truncation of A-stable Runge--Kutta discretizations in time [PDF]
We consider semilinear evolution equations for which the linear part is normal and generates a strongly continuous semigroup and the nonlinear part is sufficiently smooth on a scale of Hilbert spaces.

Semidiscretization for a Doubly Nonlinear Parabolic Equation Related to the p(x)-Laplacian
This paper studies a time discretization for a doubly nonlinear parabolic equation related to the p(x)-Laplacian by using Euler-forward scheme. We investigate existence, uniqueness, and stability questions and prove existence of the global compact ...

Near-optimal perfectly matched layers for indefinite Helmholtz problems
A new construction of an absorbing boundary condition for indefinite Helmholtz problems on unbounded domains is presented. This construction is based on a near-best uniform rational interpolant of the inverse square root function on the union of a ...
