Hyperbolic Problems and Regularity Questions

This book discusses new challenges in the quickly developing field of hyperbolic problems. Particular emphasis lies on the interaction between nonlinear partial differential equations, functional analysis and applied analysis as well as mechanics.

The book originates from a recent conference focusing on hyperbolic problems and regularity questions. It is intended for researchers in functional analysis, PDE, fluid dynamics and differential geometry.

Originating from a recent conference focusing on hyperbolic problems and regularity questions Contains study of singularities at boundaries, regularity in time for fluid flows, analytical regularity for nonlinear hypoelliptic equations, among others Includes supplementary material: sn.pub/extras
