This set of lecture notes was once written for a Nachdiplom-Vorlesungen path given on the Forschungsinstitut fUr Mathematik (FIM), ETH Zurich, throughout the Fall Semester 2000. i want to thank the college of the maths division, and particularly Rolf Jeltsch and Michael Struwe, for giving me this type of nice chance to carry the lectures in a truly stimulating atmosphere. a part of this fabric was once additionally taught past as a sophisticated graduate direction on the Ecole Poly strategy (Palaiseau) in the course of the years 1995-99, on the Instituto stronger Tecnico (Lisbon) within the Spring 1998, and on the college of Wisconsin (Madison) within the Fall 1998. This undertaking all started in the summertime 1995 whilst I gave a sequence of lectures on the Tata Institute of primary learn (Bangalore). One major target during this path is to supply a self-contained presentation of the well-posedness thought for nonlinear hyperbolic platforms of first-order partial differential equations in divergence shape, also known as hyperbolic structures of con servation legislation. Such equations come up in lots of parts of continuum physics whilst basic stability legislation are formulated (for the mass, momentum, overall power . . . of a fluid or strong fabric) and small-scale mechanisms could be overlooked (which are brought on by way of viscosity, capillarity, warmth conduction, corridor influence . . . ). ideas to hyper bolic conservation legislation convey singularities (shock waves), which seem in finite time even from soft preliminary data.
