Abstract:
I will discuss the dynamical Andre-Oort conjecture proposed by Baker-DeMarco, focusing on a case suggested by Ingram and recently proved by Ghioca, Nguyen, Ye, and myself: if C is a rational plane curve containing infinitely many points (a,b) for which z^d+a and z^d + b are both post-critically finite, then C is a fiber, or the zero locus of h(x) = Ax for some (d-1)st root of unity A.Date: Tuesday, February 17, 2015
