## Rationally connected varieties over finite fields

János Kollár

Abstract of talk for the UM/OSU Seminar

Let X be a rationally connected variety over a finite field F.
Given two F-points of X, is there a rational curve in X (defined over
F) passing through these two points?

The answer to this question (and its generalizations) solve some
conjectures of Colliot-Thélène on R-equivalence and on
the Chow group of zero cycles.
