Differential geometry and its applications

We classify the triples H ⊂ K ⊂ G of nested compact Lie groups which satisfy the "positive triple" condition that was shown in [17] to ensure that G/H admits a metric with quasi-positive curvature. A few new examples of spaces that admit quasi-positively curved metrics emerge from this classification; namely, a CP 2 -bundle over S 6 , a B 7 -bundle over HP 2 , a CP 2n−1 -bundle over HP n for each n 2, and a family of finite quotients of T 1 S 6 .
