DESCRIPTION:Title: Quasilinear systems and multiple Riemann waves\n\nAbstra
 ct: In this talk I will focus on the connection between two seemingly unre
 lated concepts for solving a general form of\n	first-order hyperbolic quasi
 linear systems of PDEs in many dimensions. These concepts are based on a v
 ariant of the\n	conditional symmetry method and on the generalized method o
 f characteristics. I will present the outline of recent results on multipl
 e Riemann wave solutions of these systems. An auxiliary result concerning 
 a modification of the Frobenius theorem will be established. We use this r
 esult to obtain formulae describing the k-wave solutions in closed form. T
 hese theoretical considerations are illustrated by examples of hydrodynami
 c-type systems.\n\nCRM-Salle 4336-4384\, Pav. André Aisenstadt\n
