Giovanni Gallavotti (Dipartimento di Fisica, Università di Roma La Sapienza, Italia). L'équation de Navier-Stokes et la réversibilité.

Microscopic reversibility might imply the possibility of a macroscopic description of friction phenomena. This will be illustrated in a general framework and some evidence for existence of reversible macroscopic equations for fluid motions equivalent to the usual dissipative Navier Stokes equations.
