Rational and non-rational varieties
Abstract: Pythagorean triples are given by rational parametrization of
the unit circle. Similarly, all conics in the plane admits a similar
parametrization. This is no longer the case for the curves of higher
For example, non-singular plane cubic curves (elliptic curves) cannot
be rationally parametrized. In dimension one and two, the problem of
existence of such parametrization is completely solved.
In higher dimensions, the picture is less clear. In this talk, I will survey
know results and open problems in this direction.
