Produktbeschreibung

The mathematical theory of the Navier-Stokes equations presents fundamental open questions that represent many challenges for the interested mathematicians. This volume contains a series of articles whose objective is to furnish new contributions and ideas to these questions, with particular regard to turbulence modelling, regularity of solutions to the initial-value problem, flow in region with an unbounded boundary, and compressible flow.
