A Lamperti-type representation of continuous-state branching processes with immigration
M. Emilia Caballero, José Luis Pérez Garmendia, Gerónimo Uribe Bravo
Guided by the relationship between the breadth-first walk of a rooted tree and its sequence of generation sizes, we are able to include immigration in the Lamperti representation o…
On selection criteria for problems with moving inhomogeneities
Michael Herrmann, Hartmut Schwetlick, Johannes Zimmer
We study mechanical problems with multiple solutions and introduce a thermodynamic framework to formulate two different selection criteria in terms of macroscopic energy production…
Modeling Non-Stationary Processes Through Dimension Expansion
Luke Bornn, Gavin Shaddick, James V Zidek
In this paper, we propose a novel approach to modeling nonstationary spatial fields. The proposed method works by expanding the geographic plane over which these processes evolve i…
Snaking and isolas of localised states in bistable discrete lattices
Chris Taylor, Jonathan H. P. Dawes
We consider localised states in a discrete bistable Allen-Cahn equation. This model equation combines bistability and local cell-to-cell coupling in the simplest possible way. The…
Tuning Tempered Transitions
Gundula Behrens, Nial Friel, Merrilee Hurn
The method of tempered transitions was proposed by Neal (1996) for tackling the difficulties arising when using Markov chain Monte Carlo to sample from multimodal distributions. In…
Darboux transforms and simple factor dressing of constant mean curvature surfaces
F. E. Burstall, J. F. Dorfmeister, K. Leschke +1
We define a transformation on harmonic maps from a Riemann surface into the 2-sphere which depends on a complex parameter, the so-called mu-Darboux transformation. In the case when…
