On components of the tensor square of a Weyl module
Shiliang Gao, Dinglong Wang
For a simple Lie algebra of type or , we give a characterization of the set of dominant integral weights such that for any rational point …
Bondi-Sachs metrics and Photon Rockets
Huabin Ge, Mingxing Luo, Qiping Su +2
We study the Bondi-Sachs rockets with nonzero cosmological constant. We observe that the acceleration of the systems arises naturally in the asymptotic symmetries of (anti-) de Sit…
Gravitational collapse of spherically symmetric stars in noncommutative general relativity
Wen Sun, Ding Wang, Naqing Xie +2
Gravitational collapse of a class of spherically symmetric stars are investigated. We quantise the geometries describing the gravitational collapse by a deformation quantisation pr…
Exact solutions of noncommutative vacuum Einstein field equations and plane-fronted gravitational waves
Ding Wang, R. B. Zhang, Xiao Zhang
We construct a class of exact solutions of the noncommutative vacuum Einstein field equations, which are noncommutative analogues of the plane-fronted gravitational waves in classi…
Quantum deformations of Schwarzschild and Schwarzschild-de Sitter spacetimes
Ding Wang, R. B. Zhang, Xiao Zhang
A quantum Schwarzschild spacetime and a quantum Schwarzschild-de Sitter spacetime with cosmological constant are constructed within the framework of a noncommutative Riemannian…
