Hydrodynamic limit fluctuations of super-Brownian motion with a stable catalyst
Klaus Fleischmann, Peter Moerters, Vitali Wachtel
We consider the behaviour of a continuous super-Brownian motion catalysed by a random medium with infinite overall density under the hydrodynamic scaling of mass, time, and space.…
Renormalization analysis of catalytic Wright-Fisher diffusions
K. Fleischmann, J. M. Swart
Recently, several authors have studied maps where a function, describing the local diffusion matrix of a diffusion process with a linear drift towards an attraction point, is mappe…
Trimmed trees and embedded particle systems
Klaus Fleischmann, Jan M. Swart
In a supercritical branching particle system, the trimmed tree consists of those particles which have descendants at all times. We develop this concept in the superprocess setting.…
Continuum-sites stepping-stone models, coalescing exhcangeable partitions, and random trees
Peter Donnelly, Steven N. Evans, Klaus Fleischmann +2
Analogues of stepping--stone models are considered where the site--space is continuous, the migration process is a general Markov process, and the type--space is infinite. Such pro…
Finite time extinction of super-Brownian motions with catalysts
Donald A. Dawson, Klaus Fleischmann, Carl Mueller
Consider a catalytic super-Brownian motion with finite variance branching. Here `catalytic' means that branching of the reactant is only possible in the presence of som…
