摘要

In this Note, we prove the existence of strong solutions to the Navier-Stokes equations for incompressible viscous fluids in a general regular bounded domain of R3 on a "short" time interval (0,T0), independent of the viscosity and of the friction between the fluid and the boundary. The solutions to the Navier-Stokes problem satisfy the inhomogeneous Navier's boundary condition and they reveal a remarkable structure of approximation of the solution to the Euler problem, which enables us to solve completely the question of the inviscid limit of the family of obtained solutions on the time interval .
