Sylvia Carlisle to give April 16th Colloquium

A metric space X is a real tree if between any two points in X there is a unique arc, and that arc is a geodesic segment. An isometry on a real tree is hyperbolic if it has no fixed points. In this talk, I will discuss the continuous theory of real trees with hyperbolic isometries, and discuss the model companion for that theory. As time allows I will talk about some properties of this model companion.
