Abstract: The nonlinear wave phenomenon appears in a wide range of applications in sciences and engineering, including fluid dynamics, elastodynamics, electromagnetic, and other fields. The study of partial differential equations modeling nonlinear wave propagation and interaction involves an interplay between the pure mathematical theory, numerical methods, and mathematical physics. An interesting feature of these equations is that solutions could become irregular even for smooth initial and boundary data and one of the challenges in the study of such solutions is to select physically meaningful solutions.

Recently, there has been lot of progress in the study of these equations and the purpose of this mini-symposium is to bring together mathematicians working on various problems both from theoretical and numerical perspectives. Some of the topics to be discussed include analysis of solutions to eikonal-type equations; study of existence, uniqueness, and stability of subsonic flows past an airfoil governed by the Euler gas dynamics equations; analysis of solutions to the two-layer quasigeotropic model; as well as convergence analysis of a large time step numerical method for conservation laws and numerical schemes for modified Buckley-Leverett equations and the black oil problem in porous media.
