Abstract: Abstract Let T be the regular tree in which every vertex has exactly $d\ge 3$ neighbours. Run a branching random walk on T, in which at each time step every particle gives birth to a… read more here.

Abstract: Seasonal snow and ice melt strongly influence glacier mass balance, yet sparse sub‐annual observations limit our understanding of seasonal dynamics. Here we construct and analyze weekly snow cover time series for 200 glaciers across western… read more here.

Abstract: The cover-time problem, i.e., the time to visit every site in a system, is one of the key issues of random walks with wide applications in natural, social, and engineered systems. Addressing the full distribution… read more here.
