DESCRIPTION:Speaker: Siddharth Kannan (MIT)\n\nTitle: Radially aligned stab
 le curves and applications\n\nAbstract:\n\nI will discuss a combinatoriall
 y defined blow-up of the moduli space of curves in genus g <= 1 and then d
 escribe two applications of this construction. The first application is mo
 re combinatorial: a modular understanding of the blow-up leads to a calcul
 ation scheme for the S_n-representations defined by the Chow ring of the b
 raid matroid. The second application is more geometric: a combinatorial un
 derstanding of the boundary complex of the blow-up leads to a calculation 
 of the weight zero subspace of the compactly-supported cohomology of the m
 oduli space M_1\,n(P^r\, d)\, which parameterizes degree d maps from smoot
 h pointed genus one curves to P^r. The talk will be based on separate join
 t projects\, with Lukas Kühne and with Terry Song.
