Resurgence of the Kontsevich-zagier Series

چکیده
We give an explicit formula for the Borel transform of the power series when q = e1/x from which its analytic continuation, its singularities (all on the positive real axis) and the local monodromy can be manifestly determined. We also give two formulas (one involving the Dedekind eta function, and another involving the complex error function) for the right, left and median summation of the Borel transform. We also prove that the limiting values of the median sum at rational multiples of 1/(2πi) coincide with the values of f(q) at the corresponding complex roots of unity. Our resurgence theorem extends more generally to the power series of torus knots and Seifert fibered 3-manifolds associated by Quantum Topology.

Resurgence of the Kontsevich-zagier Power Series
Abstract. Perturbative quantum field theory associates formal power series invariants to knotted objects, that is to knots or homology 3-spheres. These formal power series are known to be Gevrey, and are expected to be factorially divergent, and somehow linked to quantum invariants of knotted objects at complex roots of unity. The latter are the well-known Witten-Reshetikhin-Turaev invariants o...
متن کاملDedekind sums : a combinatorial - geometric viewpoint Matthias Beck and Sinai Robins
The literature on Dedekind sums is vast. In this expository paper we show that there is a common thread to many generalizations of Dedekind sums, namely through the study of lattice point enumeration of rational poly-topes. In particular, there are some natural finite Fourier series which we call Fourier-Dedekind sums, and which form the building blocks of the number of partitions of an integer...
متن کاملIdentities for the Ramanujan Zeta Function
We prove formulas for special values of the Ramanujan tau zeta function. Our formulas show that L(∆, k) is a period in the sense of Kontsevich and Zagier when k ≥ 12. As an illustration, we reduce L(∆, k) to explicit integrals of hypergeometric and algebraic functions when k ∈ {12, 13, 14, 15}.
متن کاملTransformations of L-values
In our recent work with M. Rogers on resolving some Boyd’s conjectures on two-variate Mahler measures, a new analytical machinery was introduced to write the values L(E, 2) of L-series of elliptic curves as periods in the sense of Kontsevich and Zagier. Here we outline, in slightly more general settings, the novelty of our method with Rogers, and provide a simple illustrative example. Throughou...
متن کاملMahler Measure and the Wz Algorithm
We use the Wilf-Zeilberger method to prove identities between Mahler measures of polynomials. In particular, we offer a new proof of a formula due to Laĺın, and we show how to translate the identity into a formula involving elliptic dilogarithms. This work settles a challenge problem proposed by Kontsevich and Zagier in their paper “Periods” [14].
