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…

Explicit linearization of multi-dimensional germs and vector fields through Ecalle's tree expansions

Frédéric Fauvet, Frédéric Menous, David Sauzin

We revisit the Siegel linearization problem by means of explicit formulas of non-recursive type for the linearizing transformations of a non-resonant holomorphic germ of diffeomorp…

Geometric normalization

Alain Chenciner, David Sauzin, Qiaoling Wei

For a local analytic diffeomorphism of the plane with an irrational elliptic fixed point at 0, we introduce the notion of ``geometric normalization'', which includes the classical…

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…

Resurgence and Mould Calculus

David Sauzin

Resurgence Theory and Mould Calculus were invented by J. Ecalle around 1980 in the context of analytic dynamical systems and are increasingly more used in the mathematical physics…
