An exotic sphere with positive sectional curvature

Abstract

We show that there is a metric on the Gromoll-Meyer sphere with positive sectional curvature.

A referee discovered an error in the statement of Theorem 5.3. This error is corrected and the result is renamed, Lemma 5.3. A coarse outline has been added at the end of the introduction. 95 pages
