Algebra Seminar

Mori and nef cones of moduli spaces of pointed curves

Ian Morrison

6th June, 12:05-12:55pm, Carslaw 373


I will first explain the "F-conjecture" which characterizes the extremal rays of the Mori cone of effective curves on the moduli space of n-pointed curves of genus g. Then I will review the consequences of this conjecture for the nef and ample cones of these spaces, explain reductions from the case of general genus to genus 0 and their use to prove the conjecture when g+n is small, and give some applications.

After the seminar we will take the speaker to lunch.

See the Algebra Seminar web page for information about other seminars in the series.
