Preconditioners based on ?Parareal? Time-Domain Decomposition ...
Abstract We consider optimization problems governed by time-dependent parabolic PDEs and discuss the construction of parallel preconditioners based. Télécharger
Solution Techniques for the Stokes System: A Priori and A Posteriori ...This article proposes modifications to standard low order finite element ap- proximations of the Stokes system with the goal of improving both the approximation. Hamburger BeiträgeAn appropriate choice is therefore the L2 projection of the control space to a lower level, which is realised approximately by a simple an l2 analysis of the boltzmann-grad limitThe linear collision operator L defined by (A.1) is a nonnegative un- bounded self-adjoint operator on L2(Mdv) with domain. D(L) = {g ? L2(Mdv)|ag ? L2(Mdv)} = Convergence of a finite volume scheme for the compressible Navier ...We have constructed solution on a space-periodic domain ?. When considering a polyhedral domain, the existence of smooth solutions remains open and may be a A Domain Decomposition Method for Elliptic Boundary Value ...The fact that the consistent pressure Poisson operator is an L² operator makes it harder to invert than the standard (H¹) Laplace operator. A domain Approximating L2-signatures by their compact analoguesFor smooth manifolds with boundary, the L2-signature of course is defined in terms of the intersection pairing on L2-homology.
