A multi-Poisson structure on a Lie algebra $\mathfrak{g}$ provides a systematic way to construct completely integrable Hamiltonian systems on $\mathfrak{g}$ expressed in Lax form $\partial X_\lambda /\partial t = [X_\lambda , A_\lambda ]$ in the sense of the isospectral deformation, where $X_\lambda , A_\lambda \in \mathfrak{g}$ depend rationally on the indeterminate $\lambda $ called the spectral parameter. In this paper, a method for modifying the isospectral deformation equation to the Lax…

Isomonodromic deformations of a rational differential system and reconstruction with the topological recursion: The sl2 case

In this paper, we show that it is always possible to deform a differential equation ∂xΨ(x) = L(x)Ψ(x) with L(x)∈sl2(C)(x) by introducing a small formal parameter ℏ in such a way that it satisfies the

Multi-component Painlev\'{e} ODE's and related non-autonomous KdV stationary hierarchies

First, starting from two hierarchies of autonomous St¨ackel ODE’s, we reconstruct the hierarchy of KdV stationary systems. Next, we deform considered autonomous St¨ackel systems to non-autonomous

Poisson-Nijenhuis Structures and Sato Hierarchy

We show that the direct sum of n copies of a Lie algebra is endowed with a sequence of affine Lie-Poisson brackets, which are pairwise compatible and define a multi-Hamiltonian structure; to this

The so called “Painlevé-Calogero correspondence” relates the sixth Painlevé equation with an integrable system of the Calogero type. This relation was recently generaized to the other Painlevé

The second Painlev? hierarchy is defined as the hierarchy of ordinary differential equations obtained by similarity reduction from the modified Korteweg-de Vries hierarchy. Its first member is the

A new expression of such Painleve hierarchies as (P34)-hierarchy is presented, which is more suited for WKB analysis and is also useful in studying relations between (PJ)m and degenerate Garnier systems.
