Degeneracy of Planar 4-body Kite Central Configurations: Restricted and Full Space Perspective

Shanzhong Sun, Zhifu Xie, Peng You

Based on our previously proposed direct approach to central configurations in the full configuration space, we study the degeneracy of planar four-body kite central configurations…

A proof of Witten's asymptotic expansion conjecture for WRT invariants of Seifert fibered homology spheres

Jørgen Ellegaard Andersen, Li Han, Yong Li +3

Let be a general Seifert fibered integral homology -sphere with exceptional fibers. For every root of unity , we show that the SU(2) WRT invariant of ev…

Degeneracy of Planar Central Configurations in the -Body Problem

Shanzhong Sun, Zhifu Xie, Peng You

The degeneracy of central configurations in the planar -body problem makes their enumeration problem hard and the related dynamics appealing. To truly understand the bifurcation…

Resurgence in the Universal Structures in B-model Topological String Theory

Yong Li, David Sauzin, Shanzhong Sun

We propose a systematic analysis of Alim-Yau-Zhou's double scaling limit and Couso-Santamaría's large radius limit for the perturbative free energies in B-model topological string…

On the Hadamard inverse of a resurgent function with only one singularity

Yong Li, David Sauzin, Shanzhong Sun

This note discusses the location of the singularities of the Hadamard inverse of an endlessly continuable function, in the case when the original function has only one singular sin…
