Algebraic Geometry Seminar | The Kodaira dimension of the moduli space of curves: geometric and tropical aspects

Time:2023-12-1, FRIDAY 15:30-16:30

Venue:Zoom Meeting ID: 455 260 1552 Passcode: YMSC;Tsinghua West Stepping Classroom 清华西阶梯教室

Organizer:Caucher Birkar,曲三太, 陈炳仪

Speaker:Gavril Farkas Humboldt-Universität zu Berlin

Abstract:

It is one of the landmark results in algebraic geometry of the 20th century that the moduli space M_g of curves of genus g is a variety of general type when g>23. I will discuss joint work with Jensen and Payne proving that both moduli spaces M_22 and M_23 are of general type, highlighting both the geometrical and the novel tropical aspects related to this circle of ideas.


About the Speaker:

My field of work is algebraic geometry. A significant part of my research is concerned with the study of the geometry and topology of various moduli spaces. Among other things, I am interested in moduli of curves, enumerative geometry, syzygies of algebraic varieties and commutative algebra aspects, vector bundles on curves, abelian varieties and theta functions, Prym varieties, K3 surfaces and Brill-Noether type problems, geometric group theory and resonance varieties.

      Differential geometric PDE moduli spaces: derived enhancements, ellipticityand representability | BIMSA AG Seminar

      AbstractAll sorts of algebro-geometric moduli spaces (of stable curves, stable sheaves on a CY 3-foldsflat bundles, Higgs bundles..) are best understood as objects in derived geometry. Derivedenhancements of classical moduli spaces give transparent and intrinsic meaning to previously ad-hoc structures pertaining to, for instance, enumerative geometry and are indispensable for more formore advan...
