Two Regularized Determinants of Laplacian through Resurgence theory

Wen Shen, Shanzhong Sun

We study two types of regularizations of the determinant of Laplacian on Riemann manifold from the viewpoint of resurgence theory. One is the formal logarithmic derivative of the d…

On the Uniqueness of Convex Central Configurations in the Planar -Body Problem

Shanzhong Sun, Zhifu Xie, Peng You

In this paper, we provide a rigorous computer-assisted proof (CAP) of the conjecture that there exists a unique convex central configuration for any four fixed positive masses in a…

Monodromy of Complexified Planar Kepler Problem

Shanzhong Sun, Peng You

The planar Kepler problem is complexified and we show that this holomorphic completely integrable Hamiltonian system has nontrivial monodromy.

A Weak -Functor in Morse Theory

Shanzhong Sun, Chenxi Wang

In the spirit of Morse homology initiated by Witten and Floer, we construct two -categories and . The weak one comes out of the Mor…

Resurgence and Partial Theta Series

Li Han, Yong Li, David Sauzin +1

We consider partial theta series associated with periodic sequences of coefficients, of the form , with non-negative integer and an …

Elliptic fixed points with an invariant foliation: Some facts and more questions

Alain Chenciner, David Sauzin, Shanzhong Sun +1

We address the following question: let F:(R^2,0)->(R^2,0) be an analytic local diffeomorphism defined in the neighborhood of the non resonant elliptic fixed point 0 and let Φbe a f…

On the Moyal Star Product of Resurgent Series

Yong Li, David Sauzin, Shanzhong Sun

We analyze the Moyal star product in deformation quantization from the resurgence theory perspective. By putting algebraic conditions on Borel transforms, one can define the space…

Hadamard Product and Resurgence Theory

Yong Li, David Sauzin, Shanzhong Sun

We discuss the analytic continuation of the Hadamard product of two holomorphic functions under assumptions pertaining to Ecalle's Resurgence Theory, proving that if both factors a…

The Baker-Campbell-Hausdorff formula via mould calculus

Shanzhong Sun, Yong Li, David Sauzin

The well-known Baker-Campbell-Hausdorff theorem in Lie theory says that the logarithm of a noncommutative product e X e Y can be expressed in terms of iterated commutators of X and…

Non-Embedding Theorems of Nilpotent Lie groups and Sub-Riemannian Manifolds

Yonghong Huang, Shanzhong Sun

We prove that there do not exist quasi-isometric embeddings of connected nonabelian nilpotent Lie groups equipped with left invariant Riemannian metrics into a metric measure space…

Gutzwiller's Semiclassical Trace Formula and Maslov-Type Index Theory for Symplectic Paths

Shanzhong Sun

Gutzwiller's famous semiclassical trace formula plays an important role in theoretical and experimental quantum mechanics with tremendous success. We review the physical derivation…

Symmetry of Planar Four-Body Convex Central Configurations

Alain Albouy, Yanning Fu, Shanzhong Sun

We study the relationship between the masses and the geometric properties of central configurations. We prove that in the planar four-body problem, a convex central configuration i…
