Abstract: We will explain a certain natural way to project elements of
the mapping class to simple closed curves on subsurfaces. Generalizing
a coordinate system on hyperbolic space, we will use these projections
to describe a way to characterize elements of the mapping class group
in terms of these projections. This point of view is useful in several
applications; time permitting we shall discuss how we have used this
to prove the Rapid Decay property for the mapping class group. This
talk will include joint work with Kleiner, Minksy, and Mosher.
