A bijective topological recursion for maps

Gaëtan Borot, Gaëtan Borot, Alessandro Giacchetto +2

We prove bijectively a recursive excision formula for maps of arbitrary topology. This yields the topological recursion formulae governing their enumeration, already at the level o…

Reconstruction of F-cohomological field theories on moduli of compact type

Gaëtan Borot, Silvia Ragni, Paolo Rossi

We prove an analogue of Givental-Teleman reconstruction for F-cohomological field theories on the moduli space of compact type. We apply it to reconstruct the restriction of the ex…

Macroscopic asymptotics in discrete beta-ensembles and random tilings

Gaëtan Borot, Vadim Gorin, Alice Guionnet

We carry out the asymptotic analysis of repulsive ensembles of N particles which are discrete analogues of continuous 1d log-gases or beta-ensembles of random matrix theory. The en…

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…

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…

Symmetries of F-cohomological field theories and F-topological recursion

Gaëtan Borot, Alessandro Giacchetto, Giacomo Umer

We define F-topological recursion (F-TR) as a non-symmetric version of topological recursion, which associates a vector potential to some initial data. We describe the symmetries o…
