How does this answer the question? | |
Jan 16, 2016 at 8:04 | comment | added | YCor | By the way only one half (the half you use) of result attributed to Soardi and Woess is correct: while the isometry group of a transitive locally finite connected amenable group is amenable (as a locally compact group), the converse does not hold. | |
Jan 16, 2016 at 2:02 | comment | added | YCor | Should be read: "any amenable locally compact group carries a random walk with trivial Poisson boundary", and "a closed group of isometries of a proper hyperbolic space is amenable iff it's elementary". | |
