Positive biorthogonal curvature on $S^{2} \times T^{2}$

Zhiqi Chen, Hui Zhang

We construct explicit Riemannian metrics with positive biorthogonal curvature on $S^{2} \times T^{2}$ , answering a question of Bettiol. In particular, positive biorthogonal curvature on…

Curvatures of metric Jordan algebras

Hui Zhang, Zaili Yan, Zhiqi Chen

In this paper, we investigate metric Jordan algebras, and follow the lines of the paper (J. Milnor: Curvatures of left invariant metrics on Lie groups. Adv. Math. (1976)). Firstly,…
