DESCRIPTION:Abstract: "The vanishing viscosity problem consists of underst
anding the limit\, or limits\, of solutions of the Navier–Stokes equatio
ns\, with viscosity $\\nu$\, as $\\nu$ tends to zero. The Navier–Stokes
equations are a model for real-world fluids and the parameter $\\nu$ repre
sents the ratio of friction\, or resistance to shear\, and inertia. Ultima
tely\, the relevant question is whether a real-world fluid with very small
viscosity can be approximated by an ideal fluid\, which has no viscosity.
\nIn this talk we will be primarily concerned with the classical open prob
lem of the vanishing viscosity limit of fluid flows in domains with bounda
ry. We will explore the difficulty of this problem and present some known
results. We conclude with a discussion of criteria for the vanishing visco
sity limit to be a solution of the ideal fluid equations."\n\n \n \n\n\n
