September 24, 2009	James M^cKernan Title Compactifying M_{0,n} and beyond Abstract: I will give a general overview of the material covered in the papers by Hacking, Keel and Tevelev.
October 1, 2009	David Speyer Title Chow quotients 0 Abstract:
October 22, 2009	Kartik Venakatram Title Higher-Dimensional Analogues of Stable Curves Abstract:
October 29, 2009	Kartik Venakatram Title Moduli of Hyperplane Arrangements via Chow Quotients Abstract:
November 5, 2009	Yoonsuk Hyun Title Compacification of tori Abstract:
November 17, 2009	Brian Lehmann Title Visible Contours Abstract: We will look at visible contours in the paper "Chow Quotients I" by Kapranov. Our goal will be to understand their geometry and how they relate to hyperplane arrangements.
