In Question 9.1 of his survey "Euclidean vs. Graph Metric" (2013), Benjamini considers first-passage percolation on the hierarchical graphs G_n obtained by replacing, recursively, every edge by one edge followed by two parallel edges. With independent positive edge weights of law ξ, the source–sink distance satisfies D...

We prove that the standard Cayley graph of every finite-rank Coxeter system has trivial A-homotopy groups in all degrees at least two. The argument replaces the Coxeter group by the right-angled Coxeter group that retains exactly its commuting relations. All short closed walks lift to the resulting cover, while every f...

Problem 1.16 of Ohtsuki's list (E. Ferrand, A. Stoimenow) asks whether every alternating link L satisfies σ(L) ≥ min deg_l P_L ≥ min deg_a F_L(a^-1, z), where σ is the signature, P_L(l, m) the HOMFLY polynomial and F_L(a, z) the Kauffman polynomial. Both inequalities are in print: the second is a corollary of Rutherfor...

In a problem contribution (Arnold Math. J. 7 (2021)), D. Fuchs stated seven conjectures on the billiard trajectories in a regular n-gon which join two vertices (short trajectories) and on their n − 2 types A_0, ..., A_{n−3}, on closed trajectories, and on geodesics on the regular dodecahedron. We decide all seven. The...

Every finite bipartite simple graph occurs as a vertex-induced unrooted subgraph of the principal graph of an irreducible finite-depth inclusion of hyperfinite type II1 factors. For part sizes m and n, an explicit neighborhood-multiplicity parameter q gives index q3^n, with q at most m+1, and depth at most four. The se...
