The distributed Lagrange multipliers based fictitious domain method for the numerical computation of state problems presented in Part I is now used in the frame of shape optimization. Practical aspects of this approach are discussed. In general it is

Fictitious domain approaches are an attractive way to overcome the usual drawbacks of the so-called boundary variation technique for solving optimal shape problems. In the first part of this paper, we introduce fictitious domain methods with distribu

In this paper we develop and analyse a new a posteriori error estimator for general Friedrichs' systems valid for most classical finite element approximations. This error estimator is based on comparison between an appropriate norm of the exact error

On propose une generalisation de l'estimateur a posteriori hierarchique de Bank-Weiser aux formulation mixtes, dans le cas d'approximations conformes et non conformes, avec ou sans integration numerique. On presente comme exemples d'application: la f

In the framework of adaptive methods, bases of hierarchical type are used in the \(p\)-version of the finite element method. We study the matrices corresponding to the commonly used basis, introduced by Babuska and Szabo, in the case of \(d\)-dimensi

The constant γ in the strengthened Cauchy-Buniakowski-Schwarz (C.B.S.) inequality plays a crucial role in the convergence rate of multilevel iterative methods as well as in the efficiency of a posteriori error estimators, that is in the framework of
