Sommario/riassunto

Substantial effort has been drawn for years onto the development of (possibly high-order) numerical techniques for the scalar homogeneous conservation law, an equation which is strongly dissipative in L1 thanks



to shock wave formation. Such a dissipation property is generally lost when considering hyperbolic systems of conservation laws, or simply inhomogeneous scalar balance laws involving accretive or space-dependent source terms, because of complex wave interactions. An overall weaker dissipation can reveal intrinsic numerical weaknesses through specific nonlinear mechanisms: Hugoniot curves being deformed by local averaging steps in Godunov-type schemes, low-order errors propagating along expanding characteristics after having hit a discontinuity, exponential amplification of truncation errors in the presence of accretive source terms... This book aims at presenting rigorous derivations of different, sometimes called well-balanced, numerical schemes which succeed in reconciling high accuracy with a stronger robustness even in the aforementioned accretive contexts. It is divided into two parts: one dealing with hyperbolic systems of balance laws, such as arising from quasi-one dimensional nozzle flow computations, multiphase WKB approximation of linear Schrödinger equations, or gravitational Navier-Stokes systems. Stability results for viscosity solutions of onedimensional balance laws are sketched. The other being entirely devoted to the treatment of weakly nonlinear kinetic equations in the discrete ordinate approximation, such as the ones of radiative transfer, chemotaxis dynamics, semiconductor conduction, spray dynamics of linearized Boltzmann models. “Caseology” is one of the main techniques used in these derivations. Lagrangian techniques for filtration equations are evoked too. Two-dimensional methods are studied in the context of non-degenerate semiconductor models.

Sommario/riassunto

The chief threat to the UTAH BEACH landings was the German coastal battery located just to the westward of the village of St Martin De Varreville. It had been the target of air bombardment in the preceding days but the results were not known. The fate of the northern half of the operation could have turned on it; the assured destruction of the Battery became a chief preoccupation of the 502d Airborne Infantry Regiment led by Lt. Colonel Patrick Cassidy. Widely scattered in the drop Cassidy and the paratroops under him were still determined to succeed in their objectives. In this short monograph produced by the European Theater of Operation historian S.L.A. Marshall, which was based on the oral testimony collected from the men involved, we follow Cassidy and his men as they attempt to achieve their important objectives.
