Overview poster for the Master Classes in 2008.
Abstract:
The Torelli group is the subgroup of the mapping class group
consisting of mapping classes which act trivially on the first
homology group of the surface. Following preliminary work
by Birman and her collaborators, Dennis Johnson
produced a series of papers in the late 70's and early
80's which demonstrated that the Torelli group supports
a surprisingly rich theory with deep ties to both
3-manifold topology and algebraic geometry. In fact,
the Torelli group is the first group in an infinite filtration
of the mapping class group. The terms in this filtration
are linked together by the Johnson homomorphisms, whose
beautiful theory dominates the subject.
The goal of this course is to cover in detail and from
a modern prospective the foundations of the subject and
to survey its later development.
From Monday 17 March to Friday 21 March.
All lectures take place in Aud. D4.
