“Counting lines on polarized K3-surfaces”<\/p>\n
Abstract: Counting or estimating the number of lines or, more generally, low degree rational curves on a polarized algebraic surface is a classical problem going back almost 1.5 centuries. After a brief historical excurse, I will try to give an account of the considerable progress made in the subject in the last decade or so, mainly related to various (quasi-)polarizations of K3-surfaces:
\n\u2022 lines on K3-surfaces with any polarization,
\n\u2022 lines on low degree K3-surfaces with singularities,
\n\u2022 conics on low degree K3-surfaces.
\nIf time permits, I will briefly discuss other surfaces\/varieties as well.<\/p>\n
Some parts of this work are joint projects
\n(some still in progress) with Ilia Itenberg, S\u0142avomir Rams, Ali Sinan Sert\u00f6z.<\/p>\n
Date: Friday, 12 May 2023
\nTime: 15:40 (GMT+3)
\nPlace: Zoom<\/p>\n
