DESCRIPTION:Title: <a href="https://researchseminars.org/talk/Freemath/24/
 ">Cycle-valued quasi-modular forms on Kontsevich space</a>\nby Francois Gr
 eer as part of Free Mathematics Seminar\n\n\nAbstract\nOn a general ration
 al elliptic surface (fibered over $\\mathbb{P}^1$)\, the number of section
 s of height $n$ is equal to the coefficient of the Eisenstein series $E_4(
 q)$ at order $n+1$. I will describe a conjectural generalization of this f
 act\, which associates to any smooth projective variety a quasi-modular fo
 rm valued in the Chow group of its Kontsevich moduli space. The proof is i
 n progress.\n
