Hilbert's Eleventh Problem
|Date:||December 17, 2005
Cahit Arf Auditorium
Hilbert's 11-th problem asks about the representation of integers (respectively rationals) in a number field by integral (respectively rational) quadratic form. The rational case was resolved a long time ago, being the well known Hasse Minkowski theorem. The integral case is apparently much more difficult and was only resolved recently. Its solution depends on works of many people. We will describe the problem and outline its solution.
