Constructive quantization: approximation by empirical measures
Steffen Dereich, Michael Scheutzow, Reik Schottstedt
In this article, we study the approximation of a probability measure on by its empirical measure interpreted as a random quantization. As error cri…
Moments of recurrence times for Markov chains
Frank Aurzada, Hanna Doering, Marcel Ortgiese +1
We consider moments of the return times (or first hitting times) in a discrete time discrete space Markov chain. It is classical that the finiteness of the first moment of a return…
Exponential growth rate for derivatives of stochastic flows
Holger van Bargen, Michael Scheutzow, Simon Wasserroth
We show that for a large class of stochastic flows the spatial derivative grows at most exponentially fast even if one takes the supremum over a bounded set of initial points. We d…
Positive speed of propagation in a semilinear parabolic interface model with unbounded random coefficients
Patrick W Dondl, Michael Scheutzow
We consider a model for the propagation of a driven interface through a random field of obstacles. The evolution equation, commonly referred to as the Quenched Edwards-Wilkinson mo…
