Title: Cusp volume of fibered 3-manifolds

Abstract: Consider a 3-manifold M that fibers over the circle, with
fiber a punctured surface F. I will discuss some recent results that
relate the volume of a maximal cusp of M (in the hyperbolic metric) to
combinatorial properties of the arc complex of the fiber surface
F. These results can be applied to estimate the volume of closed
3-braids.
