Windings of planar random walks and averaged Dehn function

Bruno Schapira, Robert Young

We prove a sharp estimate on the expected value of the integral of the index of a simple random walk on the square or triangular lattice. This gives new lower bounds on the average…

Homological and homotopical higher-order filling functions

Robert Young

We construct groups in which FV^3(n) != δ^2(n). This construction also leads to groups G_k, k >= 3 for which δ^{k}(n) is not subrecursive.
