Stochastic stability of the Ekman spiral

Stability of Mixed Ekman - Hartmann

Nonlinear stability of Ekman boundary layers

Consider the initial value problem for the three dimensional Navier-Stokes equations with rotation in the half-space R+ subject to Dirichlet boundary conditions as well as the Ekman spiral which is a stationary solution to the above equations. It is proved that the Ekman spiral is nonlinearly stable with respect to L2-perturbations provided the corresponding Reynolds number is small enough. Mor...

Stochastic Stability

Google is a well–known search engine that employs the PageRank algorithm [9] to rank the relative importance of webpages based on the link structure of the World–Wide Web. Intutively, rankings are based on a “random–surfer” model. Despite its tremendous success, Langville and Meyer [8] have pointed out some of its drawbacks. As the web continues to grow the computation of page ranks becomes mor...

Stochastic Stability

In this talk I will introduce the principle of stochastic stability and discussing its consequences both at equilibrium and off-equilibrium.
