Title:Noise-Induced Stabilization of Planar Flows
Speaker: David Herzog (Drake University)
Time: Friday, November 7, 2014 3:30 pm
Place: MSB 109A

Abstract. We discuss certain, explosive ODEs in the plane that become stable 
under the addition of noise. In each equation, the process by which stabilization 
occurs is intuitively clear: Noise diverts the solution away from any instabilities in 
the underlying ODE. However, in many cases, proving rigorously this phenomenon 
occurs has thus far been difficult and the current methods used to do so are rather 
ad hoc. Here we present a general, novel approach to showing stabilization by 
noise and apply it to these examples. We will see that the methods used 
streamline existing arguments as well as produce optimal results, in the sense that 
they allow us to understand well the asymptotic behavior of the equilibrium 
measure at infinity.

Hope to see you, 

Iddo
