Speaker: Alexander Degtyarev (Bilkent)<\/p>\n
\u201cLinear subspaces in algebraic varieties\u201d<\/p>\n
Abstract: (partially joint with I. Itenberg and J. Ch. Ottem)
\nI will address several seemingly unrelated problems, such as the 64 lines in Schur\u2019s quartic x(x^3-y^3)=z(z^3-w^3), 72 tritangents to the plane sextic curve x^6+y^6+z^6=10(x^3y^3+y^3z^3+z^3x^3), and 405 two-spaces in Fermat\u2019s cubic four-fold x_0^3+x_1^3+ldots+x_5^3=0. The first problem is classical, whereas the two others are relatively new. I will state that the figures indicated are indeed the maxima for the respective problems, and then I will outline the proof (for the last two problems) using a reduction to the so-called Niemeier lattices.<\/p>\n
