# Generalised ordinary vs fully simple duality for $n$-point functions and a proof of the Borot--Garcia-Failde conjecture

@inproceedings{Bychkov2021GeneralisedOV, title={Generalised ordinary vs fully simple duality for \$n\$-point functions and a proof of the Borot--Garcia-Failde conjecture}, author={Boris Bychkov and Petr Dunin-Barkowski and Maxim Kazarian and Sergey Shadrin}, year={2021} }

We study a duality for the n-point functions in VEV formalism that we call the ordinary vs fully simple duality. It provides an ultimate generalisation and a proper context for the duality between maps and fully simple maps observed by Borot and Garcia-Failde. Our approach allows to transfer the algebraicity properties between the systems of n-point functions related by this duality, and gives direct tools for the analysis of singularities. As an application, we give a proof of a recent…
