Degenerate systems of three Brownian particles with asymmetric collisions: invariant measure of gaps
Thomas Dreyfus, Jules Flin, Sandro Franceschi
We consider a degenerate system of three Brownian particles undergoing asymmetric collisions. We study the gap process of this system and focus on its invariant measure. The gap pr…

Construction of ergodic IDLA forests in
Nicolas Chenavier, David Coupier, Keenan Penner +1
We prove the existence of infinite-volume IDLA forests in , with , based on a multi-source IDLA protocol. Unlike IDLA aggregates, the laws of the IDLA fore…

Equivariant spaces of matrices of constant corank one
Ada Boralevi, Daniele Faenzi, Dragoş Frăţilă
We study spaces of matrices coming from irreducible representations of reductive groups over an algebraically closed field of characteristic zero and we completely classify those o…
