On laws of large numbers for random walks
Anders Karlsson, François Ledrappier
We prove a general noncommutative law of large numbers. This applies in particular to random walks on any locally finite homogeneous graph, as well as to Brownian motion on Riemann…

The Poisson boundary of lamplighter random walks on trees
Anders Karlsson, Wolfgang Woess
Let T be the homogeneous tree with degree and G a finitely generated group whose Cayley graph is T. The associated lamplighter group is the wreath product of the cyclic group of or…

Superrigidity, generalized harmonic maps and uniformly convex spaces
T. Gelander, A. Karlsson, G. A. Margulis
We prove several superrigidity results for isometric actions on metric spaces satisfying some convexity properties. First, we extend some recent theorems of N. Monod on uniform and…
