A probabilistic interpretation and stochastic particle approximations of the 3-dimensional Navier-Stokes equations

Fontbona Torres, Joaquín · SPRINGER · 2009 · ISSN 0178-8051

We develop a probabilistic interpretation of local mild solutions of the three dimensional Navier-Stokes equation in the L-p spaces, when the initial vorticity field is integrable. This is done by associating a generaliz...
