On Noncoercive Variational Inequalities
نویسندگان
چکیده
We consider variational inequalities with different trial and test spaces and a possibly non-coercive bilinear form. Well-posedness is shown under general conditions that are e.g. valid for the space-time variational formulation of parabolic variational inequalities. Moreover, we prove an estimate for the error of a Petrov-Galerkin approximation in terms of the residual. For parabolic variational inequalities the arising estimate is independent of the final time.

L∞-error Estimate for a Noncoercive System of Elliptic Quasi-variational Inequalities: a Simple Proof
In this paper we provide a simple proof to derive L∞-error estimate for a noncoercive system of quasi-variational inequalities related to the management of energy production. The key idea is a discrete L∞-stability property owned by the corresponding coercive problem.
متن کاملOn a Noncoercive System of Quasi-variational Inequalities Related to Stochastic Control Problems
This paper deals with a system of quasi-variational inequalities with noncoercive operators. We prove the existence of a unique weak solution using a lower and upper solutions approach. Furthermore, by means of a Banach’s fixed point approach, we also prove that the standard finite element approximation applied to this system is quasi-optimally accurate in L∞.
متن کاملPointwise Error Estimate for a Noncoercive System of Quasi-variational Inequalities Related to the Management of Energy Production
This paper is devoted to the approximation by a piecewise linear finite element method of a noncoercive system of elliptic quasi-variational inequalities arising in the management of energy production. A quasi-optimal L∞ error estimate is established, using the concept of subsolution.
متن کاملSub- Supersolutions and the Existence of Extremal Solutions in Noncoercive Variational Inequalities
The paper is concerned with the solvability of variational inequalities that contain second-order quasilinear elliptic operators and convex functionals. Appropriate concepts of suband supersolutions (for inequalities) are introduced and existence of solutions and extremal solutions are discussed.
متن کاملAlgorithmic Approach for the Asymptotic Behavior of a System of Parabolic Quasi-Variational Inequalities
In this paper we evaluate the variation in L 1-norm between u i h (T; x) ; i = 1; :::; J the discrete solution calculated at the moment T and u i 1 ; the asymptotic continuous solution of the system of parabolic quasi-variational inequalities with noncoercive operators. The proof uses an algorithmic approach and the system of elliptic quasi-variational inequalities results.
