Concurring reduction schemes for Dirac structures

Dan Aguero, Alessandro Arsie, Pedro Frejlich +1

The notion of \emph{concurrence} was recently proposed as the natural compatibility relation between Dirac structures, generalizing the commutativity of two Poisson structures. We…

An involutivity theorem for a class of Poisson quasi-Nijenhuis manifolds

Eber Chuño Vizarreta, Gregorio Falqui, Igor Mencattini +1

This note aims to continue our study about the applications of Poisson quasi-Nijenhuis geometry to the theory of classical completely integrable systems. More precisely, we will pr…

On three-dimensional Poisson quasi-Nijenhuis manifolds and Haantjes structures

E. Chuño Vizarreta, I. Mencattini, M. Pedroni

In this note we first characterize Poisson quasi-Nijenhuis structures on three-dimensional oriented manifolds whose underlying Poisson tensor never vanishes. We then apply this res…

Poisson quasi-Nijenhuis manifolds, closed Toda lattices, and generalized recursion relations

Eber Chuño Vizarreta, Gregorio Falqui, Igor Mencattini +1

We present two involutivity theorems in the context of Poisson quasi-Nijenhuis %(PqN) manifolds. The second one stems from recursion relations that generalize the so called Lenard-…

What is the Magnus Expansion?

Kurusch Ebrahimi-Fard, Igor Mencattini, Alexandre Quesney

The Magnus expansion, introduced by Wilhelm Magnus in 1954, is an infinite Lie series employed to express solutions for first-order homogeneous linear differential equations involv…

A Dubrovin-Frobenius manifold structure of NLS type on the orbit space of

Alessandro Arsie, Paolo Lorenzoni, Igor Mencattini +1

Generalizing a construction presented in [3], we show that the orbit space of less the image of coordinate lines under the quotient map is equipped with two Dubrovin-Frobeniu…
