DESCRIPTION:A group with a geometric action on some hyperbolic space is ne
 cessarily word hyperbolic. We might therefore ask what can be said if we r
 elax this to acting properly by isometries but every countable group acts 
 (metrically) properly on a\nlocally finite hyperbolic graph.\n\nWe will in
 vestigate what happens when we restrict the space being acted on\, for ins
 tance to (finite products of)\nquasitrees\, combined with finiteness condi
 tions on the group (being finitely generated) and/or the action (having a 
 locally finite orbit).
