Genus expansion of matrix models and ћ expansion of KP hierarchy
Journal of High Energy Physics, 2020 We study ћ expansion of the KP hierarchy following Takasaki-Takebe [1] considering several examples of matrix model τ-functions with natural genus expansion.

Nonlinear Dynamics on the Plane and Integrable Hierarchies of Infinitesimal Deformations [PDF]
, 2002 A class of nonlinear problems on the plane, described by nonlinear inhomogeneous $\bar{\partial}$-equations, is considered. It is shown that the corresponding dynamics, generated by deformations of inhomogeneous terms (sources) is described by Hamilton ...

Integrating partonomic hierarchies in anatomy ontologies [PDF]
BMC Bioinformatics, 2004 Abstract Background Anatomy ontologies play an increasingly important role in developing integrated bioinformatics applications. One of the primary relationships between anatomical tissues represented in such ontologies is part-of.

Actions for Integrable Systems and Deformed Conformal Theories [PDF]
, 1992 I report on work on a Lagrangian formulation for the simplest 1+1 dimensional integrable hierarchies. This formulation makes the relationship between conformal field theories and (quantized) 1+1 dimensional integrable hierarchies very clear.Comment ...

Integrable hierarchies and the modular class [PDF]
Annales de l'Institut Fourier, 2008 It is well-known that the Poisson-Nijenhuis manifolds, introduced by Kosmann-Schwarzbach and Magri form the appropriate setting for studying many classical integrable hierarchies. In order to define the hierarchy, one usually specifies in addition to the Poisson-Nijenhuis manifold a bi-hamiltonian vector field.

Solution of tetrahedron equation and cluster algebras
Journal of High Energy Physics, 2021 We notice a remarkable connection between the Bazhanov-Sergeev solution of Zamolodchikov tetrahedron equation and certain well-known cluster algebra expression. The tetrahedron transformation is then identified with a sequence of four mutations.

The Journal of Nonlinear Sciences and Applications, 2017 Summary: An integrable coupling hierarchy of Dirac integrable hierarchy is presented by means of zero curvature representation. A Hamiltonian operator involving two parameters is introduced, and it is used to derive a pair of Hamiltonian operators. A bi-Hamiltonian structure of the obtained integrable coupling hierarchy is constructed with the aid of ...
