Original Announcement

This workshop will be devoted to recent developments and new directions in Teichm�ller theory from the point of view of Thurston's Lipschitz metric. Originally introduced by Thurston in an unpublished manuscript in 1986, the Lipschitz metric is an "asymmetric metric" on Teichm�ller space. The geometry of this metric is very rich, as Thurston showed in his paper; it relates to Finsler geometry, to the theory of measured laminations and foliations, and to the curve complex.

Interest in the Lipschitz metric has recently surged on several fronts. For instance, interesting connections have been made with other metrics on Teichm�ller space, with Culler-Vogtmann's Outer space, and with three-dimensional Lorentzian geometry. One of the goals of this workshop will be to bring together mathematicians working on various aspects of the subject who do not usually meet to gather and exchange information, compare and work on open problems, learn each other's techniques, and possibly open up some new fields of study. The main topics for the workshop will be:
