O-vertex, O7-plane, and Topological Vertex
Sung-Soo Kim, Xiaobin Li, Futoshi Yagi +1
We revisit the instanton partition function for 5d SO() gauge theories compactified on S, computed from the topological vertex formalism with the O-vertex ba…
Notes on Quasinormal Modes of charged de Sitter Blackholes from Quiver Gauge Theories
Pujun Liu, Rui-Dong Zhu
We give the connection formulae for ordinary differential equations with 5 and 6 (and in principle can be generalized to more) regular singularities from the data of instanton part…
Counting Bethe States in Twisted Spin Chains
Hongfei Shu, Peng Zhao, Rui-Dong Zhu +1
We present a counting formula that relates the number of physical Bethe states of integrable models with a twisted boundary condition to the number of states in the untwisted or pa…
Connection formulae in the Collision Limit I: Case Studies in Lifshitz Geometry
Hao Zhao, Rui-Dong Zhu
The connection formulae provide a systematic way to compute physical quantities, such as the quasinormal modes, Green functions, in blackhole perturbation theories. In this work, w…
