   Title: Efficient geodesics and an effective algorithm for distance in
the complex of curves

Abstract: This talk will present joint work with Dan Margalit and Joan
Birman, an algorithm for determining the distance between two vertices of
the complex of curves. While there already exist such algorithms, for
example by Leasure, Shackleton, and Webb, this approach is new, simple,
and more effective for all distances accessible by computer. The method
gives a new preferred finite set of geodesics between any two vertices of
the complex, called efficient geodesics, which are different from the
tight geodesics introduced by Masur and Minsky.
