Existence of Boutroux curves, -functions and spectral networks from Newton's polygon

Bertrand Eynard, Soufiane Oukassi

We prove the existence of an algebraic plane curve of equation , with prescribed asymptotic behaviors at punctures, and with the Boutroux property, namely, periods have v…

Lecture on the combinatorial algebraic method for computing algebraic integrals

Bertrand Eynard

Consider an algebraic equation where (or with a subfield) is a bivariate polynomial, it defines a pl…

Hirota, Fay and Geometry

Bertrand Eynard, Soufiane Oukassi

This is a review of the relationship between Fay identities and Hirota equations in integrable systems, reformulated in a geometric language compatible with recent Topological Recu…

Counting mobiles by integrable systems

Michel Bergère, Bertrand Eynard, Emmanuel Guitter +1

Mobiles are a particular class of decorated plane trees which serve as codings for planar maps. Here we address the question of enumerating mobiles in their most general flavor, in…

Generalized cycles on Spectral Curves

B. Eynard

Generalized cycles can be thought of as the extension of form-cycle duality between holomorphic forms and cycles, to meromorphic forms and generalized cycles. They appeared as an u…

Correlation Functions of Harish-Chandra Integrals over the Orthogonal and the Symplectic Groups

A. Prats Ferrer, B. Eynard, P. Di Francesco +1

The Harish-Chandra correlation functions, i.e. integrals over compact groups of invariant monomials prod tr{X^{p_1} Omega Y^{q_1} Omega^dagger X^{p_2} ... with the weight exp tr{X…
