Integrable hierarchies, Frölicher–Nijenhuis bicomplexes and Lauricella bi-flat F-manifolds
P Lorenzoni, S Perletti - Nonlinearity, 2023 - iopscience.iop.org
Given the Frölicher-Nijenhuis bicomplex (d, dL) associated with a (1, 1)-tensor field L with
vanishing Nijenhuis torsion, we define a multi-parameter family of bi-flat structures (∇ …

Tautological relations and integrable systems
We present a family of conjectural relations in the tautological cohomology of the moduli
spaces of stable algebraic curves of genus g with n marked points. A large part of these …

Moduli spaces of residueless meromorphic differentials and the KP hierarchy
We prove that the cohomology classes of the moduli spaces of residueless meromorphic

Riemann–Hilbert–Birkhoff inverse problem for semisimple flat FF‐manifolds and convergence of oriented associativity potentials
G Cotti - Journal of the London Mathematical Society, 2024 - Wiley Online Library
In this paper, we address the problem of classification of quasi‐homogeneous formal power
series providing solutions of the oriented associativity equations. Such a classification is …

Riemannian F-manifolds, bi-flat F-manifolds, and flat pencils of metrics
In this paper, we study relations between various natural structures on F-manifolds. In
particular, given an arbitrary Riemannian F-manifold, we present a construction of a …

Integrable systems of finite type from F-cohomological field theories without unit
A Buryak, D Gubarevich - Mathematical Physics, Analysis and Geometry, 2023 - Springer
One of many manifestations of a deep relation between the topology of the moduli spaces of
algebraic curves and the theory of integrable systems is a recent construction of Arsie …
