The Widom-Rowlinson model: Mesoscopic fluctuations for the critical droplet
Frank den Hollander, Sabine Jansen, Roman Kotecký +1
We study the critical droplet for a close-to-equilibrium Widom-Rowlinson model of interacting particles, represented by disks of radius , in the two-dimensional plane at low tem…

Logarithms of Catalan generating functions: A combinatorial approach
Sabine Jansen, Leonid Kolesnikov
We analyze the combinatorics behind the operation of taking the logarithm of the generating function for generalized Catalan numbers. We provide combinatorial i…
