Quasinormal Modes of C-metric from SCFTs
Yang Lei, Hongfei Shu, Kilar Zhang +1
We study the quasinormal modes (QNM) of the charged C-metric, which physically stands for a charged accelerating black hole, with the help of Nekrasov's partition function of 4d $\…
Yoneda Ext-algebras of Takeuchi smash products
Quanshui Wu, Ruipeng Zhu
We prove that the Yoneda Ext-algebra of a Takeuchi smash product is the graded Takeuchi smash product of the Yoneda Ext-algebras of the two algebras or modules involved. As an appl…
A note on the discriminant of reflection Hopf algebras
Ruipeng Zhu
We provide a formula for commputing the discriminant of skew Calabi-Yau algebra over a central Calabi-Yau algebra. This method is applied to study the Jacobian and discriminant for…
More on topological vertex formalism for 5-brane webs with O5-plane
Hirotaka Hayashi, Rui-Dong Zhu
We propose a concrete form of a vertex function, which we call O-vertex, for the intersection between an O5-plane and a 5-brane in the topological vertex formalism, as an extension…
Impacts of COVID-19 control measures on tropospheric NO over China, South Korea and Italy
Jiaqi Chen, Zhe Jiang, Kazuyuki Miyazaki +6
Tropospheric nitrogen dioxide (NO) concentrations are strongly affected by anthropogenic activities. Using space-based measurements of tropospheric NO, here we investigate…
Closed form fermionic expressions for the Macdonald index
Omar Foda, Rui-Dong Zhu
We interpret aspects of the Schur indices, that were identified with characters of highest weight modules in Virasoro minimal models for , in terms o…
