Resurgent Structure of the Topological String and the First Painlevé Equation

Kohei Iwaki, Marcos Marino

We present an explicit formula for the Stokes automorphism acting on the topological string partition function. When written in terms of the dual partition function, our formula im…

Topological recursion and uncoupled BPS structures II: Voros symbols and the -function

Kohei Iwaki, Omar Kidwai

We continue our study of the correspondence between BPS structures and topological recursion in the uncoupled case, this time from the viewpoint of quantum curves. For spectral cur…

Topological recursion and uncoupled BPS structures I: BPS spectrum and free energies

Kohei Iwaki, Omar Kidwai

For the hypergeometric spectral curve and its confluent degenerations (spectral curves of "hypergeometric type"), we obtain a simple formula expressing the topological recursion fr…

Witten-Reshetikhin-Turaev function for a knot in Seifert manifolds

Hiroyuki Fuji, Kohei Iwaki, Hitoshi Murakami +1

In this paper, for a Seifert loop (i.e., a knot in a Seifert three-manifold), first we give a family of an explicit function whose special values at roots of unity are id…

2-parameter -function for the first Painlevé equation -Topological recursion and direct monodromy problem via exact WKB analysis-

Kohei Iwaki

We show that a 2-parameter family of -functions for the first Painlevé equation can be constructed by the discrete Fourier transform of the topological recursion partition funct…

Voros Coefficients for the Hypergeometric Differential Equations and Eynard-Orantin's Topological Recursion - Part II : For the Confluent Family of Hypergeometric Equations

Kohei Iwaki, Tatsuya Koike, Yumiko Takei

We show that the each member of the confluent family of the Gauss hypergeometric equations is realized as quantum curves for appropriate spectral curves. As an application, relatio…

Voros Coefficients for the Hypergeometric Differential Equations and Eynard-Orantin's Topological Recursion - Part I : For the Weber Equation

Kohei Iwaki, Tatsuya Koike, Yumiko Takei

We develop the theory of quantization of spectral curves via the topological recursion. We formulate a quantization scheme of spectral curves which is not necessarily admissible in…

Stokes Matrices for the Quantum Cohomologies of Orbifold Projective Lines

Kohei Iwaki, Atsushi Takahashi

We prove the Dubrovin's conjecture for the Stokes matrices for the quantum cohomology of orbifold projective lines. The conjecture states that the Stokes matrix of the first struct…
