Refined lattice point counting on the moduli space of Klein surfaces
Nitin Kumar Chidambaram, Elba Garcia-Failde, Alessandro Giacchetto +1
We introduce the moduli space of metric Möbius graphs, which extend ribbon graphs to the non-orientable world. This space contains both the moduli space of Riemann surfaces and the…
Theta classes: generalized topological recursion, integrability and -constraints
Vincent Bouchard, Nitin K. Chidambaram, Alessandro Giacchetto +1
We study the intersection theory of the -classes, where and , which are cohomological field theories obtained as the top degrees of Chiodo clas…
-Hurwitz numbers from refined topological recursion
Nitin Kumar Chidambaram, Maciej Dołęga, Kento Osuga
We prove that single -weighted -Hurwitz numbers with internal faces are computed by refined topological recursion on a rational spectral curve, for certain rationa…
Whittaker vectors at finite energy scale, topological recursion and Hurwitz numbers
Gaëtan Borot, Nitin Kumar Chidambaram, Giacomo Umer
We upgrade the results of Borot--Bouchard--Chidambaram--Creutzig to show that the Gaiotto vector in pure supersymmetric gauge theory admits an analytic conti…
-Hurwitz numbers from Whittaker vectors for -algebras
Nitin K. Chidambaram, Maciej Dołęga, Kento Osuga
We show that -Hurwitz numbers with a rational weight are obtained by taking an explicit limit of a Whittaker vector for the -algebra of type . Our result is a va…
Taking limits in topological recursion
Gaëtan Borot, Vincent Bouchard, Nitin Kumar Chidambaram +2
When does topological recursion applied to a family of spectral curves commute with taking limits? This problem is subtle, especially when the ramification structure of the spectra…
Relations on and the negative -spin Witten conjecture
Nitin Kumar Chidambaram, Elba Garcia-Failde, Alessandro Giacchetto
We construct and study various properties of a negative spin version of the Witten -spin class. By taking the top Chern class of a certain vector bundle on the moduli space of…
Shifted Witten classes and topological recursion
Séverin Charbonnier, Nitin Kumar Chidambaram, Elba Garcia-Failde +1
The Witten -spin class defines a non-semisimple cohomological field theory. Pandharipande, Pixton and Zvonkine studied two special shifts of the Witten class along two semisimpl…
Whittaker vectors for -algebras from topological recursion
Gaëtan Borot, Vincent Bouchard, Nitin Kumar Chidambaram +1
We identify Whittaker vectors for -modules with partition functions of higher Airy structures. This implies that Gaiotto vectors, describing the fundam…
Windows for cdgas
Nitin K. Chidambaram, David Favero
We study a Fourier-Mukai kernel associated to a GIT wall-crossing for arbitrarily singular (not necessarily reduced or irreducible) affine varieties over any field. This kernel is…
Kernels for Grassmann Flops
Matthew R. Ballard, Nitin K. Chidambaram, David Favero +2
We develop a generalization of the -construction of the first author, Diemer, and the third author for Grassmann flips. This generalization provides a canonical idempotent kerne…
Higher Airy structures, W algebras and topological recursion
Gaëtan Borot, Vincent Bouchard, Nitin K. Chidambaram +2
We define higher quantum Airy structures as generalizations of the Kontsevich-Soibelman quantum Airy structures by allowing differential operators of arbitrary order (instead of on…
Quantizing Weierstrass
Vincent Bouchard, Nitin K. Chidambaram, Tyler Dauphinee
We study the connection between the Eynard-Orantin topological recursion and quantum curves for the family of genus one spectral curves given by the Weierstrass equation. We constr…
Canonical structure of the E10 model and supersymmetry
Axel Kleinschmidt, Hermann Nicolai, Nitin K. Chidambaram
A coset model based on the hyperbolic Kac-Moody algebra E10 has been conjectured to underly eleven-dimensional supergravity and M theory. In this note we study the canonical struct…
