I'm a PhD student at the Department of Mathematics, University of Toronto.
Previously I studied mathematics, physics and computer science at University of Warsaw, where I obtained M. Sc. degree in mathematics.
My main interests are geometric group theory and discrete probability. I'm also interested in theoretical computer science, combinatorics and theoretical physics.

Actions of amenable groups on graphs with uncountably many ends
Thanks for the example. But still the question remains - can I have a Schreier graph with uncountably many ends to start with? |

Actions of amenable groups on graphs with uncountably many ends
Why? In any case, that's what I'm assuming - both $G$ and $S$ are amenable. |

Right, $H$ doesn't have to be normal. I've edited the question. |

Sorry, you are right, of course the action is not by isometries, I've edited the question. So the action doesn't preserve the graph structure. |

Actions of amenable groups on graphs with uncountably many ends
@YCor: I think of $S$ as being a graph with edges (and possibly loops) labelled by generators of $G$, and $G$ acting by isometries (by moving the vertices along the labelled arrows). Does that clarify what I mean here? |

Regularity of polynomial growth of groups
@YvesCornulier: any reference for that? |

Nonmonotonicity of expected distance of a random walk
A nice example. But somehow this is still not what I had in mind, see the edit in the question. |
