\u201cTritangents to sextic curves via Niemeier lattices\u201d<\/p>\n
Abstract: I will address the following conjecture (and some refinements thereof): \u201cA smooth plane curve of degree 6 has at most 72 tritangents.\u201d After a brief introduction to the subject and a survey of the known results for the other polarized K3-surfaces, I will explain why the traditional approach does not work and suggest a new one, using the embedding of the N\u00e9ron\u2014Severi lattice of a K3-surface to an appropriate Niemeier lattice. I will also discuss the pros and contras of several versions of this approach and report the partial results obtained so far.<\/p>\n
