We discuss several questions revolving around the topic: which groups have a non-constant harmonic function satisfying some kind of smallness property?
In particular we show the existence of an amenable group with a non-constant harmonic function whose gradient is going to zero at infinity.
All notions will be defined in the talk.
Joint work with Gidi Amir and Maria Gerasimova.
