Nonlinear Problems in Mathematical Physics and Related Topics II : In Honor of Professor O.A. Ladyzhenskaya (International Mathematical Series)

Connections between the regularity problem for the Navier-Stokes equations and a backward uniqueness problem for the heat operator are also clarified.
Generalizations and modified Navier-Stokes equations modeling various physical phenomena such as the mixture of fluids and isotropic turbulence are also considered.
