We look at a paper of McMullen "Braid Groups and Hodge Theory" exploring representations of braid groups and their connections to arithemetic lattices.

The goal of this talk is to study geography and classification problem for Stein fillings of contact structures supported by planar open books. In the first part we will prove that for contact structures supported by planar open books Stein fillings have a finite geography. In the second part we will outline an approach to classify Stein fillings of manifolds supported by planar open books.

We will investigate a method of "seeing" properties of four dimensional symplectic spaces by looking at two dimensional pictures. We will see how to calculate the Euler characteristic, identify embedded surfaces, see intersection numbers, and how to see induced contact structures on the boundary of these manifolds.

The main goal is to characterize the dilatation of an outer automorphisms
of free groups. It is known that for any automorphism, its dilatation is a
weak Perron number. The converse was recently shown by Thurston; for every
weak Perron number, there is an automorphism represented by a train track
map. We will discuss Thurston's theorem and its proof.

We will discuss the basics of automorphisms of free groups and train track
structure. We will define the growth rate which is a topological entropy
of the train track map.

We will prove a duality between locally compact Hausdorff spaces and the C*-algebra of continuous complex-valued functions on that space. Formally, this is the equivalence of the opposite category of commutative C*-algebras and the category of locally compact Hausdorff spaces.

The aim of the talk is to give a complete proof of the fact that any closed oriented 3-manifold has a trivial tangent bundle.
