SEMINARIO DE GEOMETRÍA: TIM RYAN (STONY BROOK UNIVERSITY)
Viernes 26 Mayo 2017, 12:00pm
Accesos : 314

Título: Persistent families of points on rational surfaces.

Expositor : Tim Ryan (Stony Brook University)

Lugar: Aula de seminarios IMATE OAXACA

Contacto: César Lozano Huerta

Resumen: In this talk we will discuss cohomology classes of a compactification of the configuration space of points on the projective plane: the Hilbert scheme.
 
We will show that many of those classes persist when we apply a birational transformation to the plane. We will provide explicit examples of many of these persistent classes and explain the geometry of them as we modify the underlying plane.
