Random skeletons in high-dimensional lattice trees
Manuel Cabezas, Alexander Fribergh, Mark Holmes +1
We study the behaviour of the rescaled minimal subtree containing the origin and K random vertices selected from a random critical (sufficiently spread-out, and in dimensions d > 8…

Rescaling the spatial lambda Fleming-Viot process and convergence to super-Brownian motion
J. Theodore Cox, Edwin A. Perkins
We show that a space-time rescaling of the spatial Lamba-Fleming-Viot process of Barton and Etheridge converges to super-Brownian motion. This can be viewed as an extension of a re…

Renormalization of the two-dimensional Lotka--Volterra model
J. Theodore Cox, Edwin A. Perkins
We show that renormalized two-dimensional Lotka--Volterra models near criticality converge to a super-Brownian motion. This is used to establish long-term survival of a rare type f…
