Ignacio Barros, Université Paris-Saclay, will be speaking.
The presentation is titled "Pencils on surfaces with normal crossings and the Kodaira dimension of Mg,n"
Contact Laure Flapan (flapanla@msu.edu) for more information.
The first half of the talk will be a colloquium style talk, where I will recall the history of the problem of determining the Kodaira dimension of the moduli space of curves. In the second half I will report on joint work with D. Agostini, where we study smoothing of pencils of curves on surfaces with normal crossings. As a consequence we obtain new instances of (g,n) where Mg,n is of negative Kodaira dimension and provide bounds for the Kodaira dimension of M16 and M12,8. more information...
