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…

Uniform bundles on generalised Grassmannians

Xinyi Fang, Duo Li, Yanjie Li

Let $E$ be a uniform bundle on an arbitrary generalised Grassmannian $X$ defined over $C$ . We show that if the rank of $E$ is at most $e . d . (VMRT)$ , then $E$ neces…

Morphisms from $P^{m}$ to flag varieties

Xinyi Fang, Peng Ren

In this paper, we consider the morphisms from projective spaces to flag varieties. We show that the morphisms can only be constant under some special conditions. As a consequence,…
