Nonexistence of Bigeodesics in Integrable Models of Last Passage Percolation
Riddhipratim Basu, Christopher Hoffman, Allan Sly
Bi-infinite geodesics are fundamental objects of interest in planar first passage percolation. A longstanding conjecture states that under mild conditions there are almost surely n…
The two-type Richardson model in the half-plane
Daniel Ahlberg, Maria Deijfen, Christopher Hoffman
The two-type Richardson model describes the growth of two competing infection types on the two or higher dimensional integer lattice. For types that spread with the same intensity,…
Cover time for the frog model on trees
Christopher Hoffman, Tobias Johnson, Matthew Junge
The frog model is a branching random walk on a graph in which particles branch only at unvisited sites. Consider an initial particle density of on the full -ary tree of heig…
