Uniform non-homogeneous bundles on quadrics

Xinyi Fang, Yuhang Zhou

Let $X$ be an $n$ -dimensional generalized Grassmannian not isomorphic to $P^{n}$ . We prove that $k (X) \leq n - 1$ , where $k (X)$ denotes the maximal integer such that every unifo…

Notes on the double Wick rotated BTZ black hole

Hua-Yu Dai, Xi-Hao Fang, Mitsutoshi Fujita

We analyze the double Wick rotated BTZ black hole with the Euclidean signature, which is a Riemannian manifold. We calculate thermodynamics, total energy of spacetime, and holograp…

Uniform bundles on quadrics

Xinyi Fang, Duo Li, Yanjie Li

We show that there exist only constant morphisms from $Q^{2 n + 1} (n \geq 1)$ to $G (l, 2 n + 1)$ if $l$ is even $(0 < l < 2 n)$ and $(l, 2 n + 1)$ is not $(2, 5)$ . As an applicati…
