If you have a question about this talk, please contact Jessica Guerand. In this talk we prove the existence of global strong solution for the Navier-Stokes equations with general degenerate viscosity coefficients in one dimension. The cornerstone of the proof is the introduction of a new effective pressure which allows to obtain an Oleinik-type estimate for the so called effective velocity. It enables us to control the $L^\infty$ norm of $\frac{1}{\rho}$ with $\rho$ the density. In our proof we make use also of additional regularizing effects on the velocity which requires to extend the techniques developed by Hoff for the constant viscosity case.
