A -analogue of the matrix fifth Painlevé system

Hiroshi Kawakami

We consider a degeneration of the -matrix sixth Painlevé system. As a result, we obtain a system of non-linear -difference equations, which describes a deformation of a certa…

A -analogue of the matrix sixth Painlevé system

Hiroshi Kawakami

We derive a -analogue of the matrix sixth Painlevé system via a connection-preserving deformation of a certain Fuchsian linear -difference system. In specifying the linear $q…

Emergence of long-term rhythmicity within a frustrated triangle oscillator-network

Masatomo Matsushima, Hiroshi Ueno, Yoshiki Kamiya +1

This study tries to simulate a brain cell network using an electric circuit oscillator called electronic firefly. Multiple stability was observed in the electric circuit oscillator…

Four-dimensional Painlevé-type difference equations

Hiroshi Kawakami

We focus on Fuchsian equations with four accessory parameters and three singular points. We see that the Fuchsian equations admit a "degeneration scheme" in some sense, which is ex…

Four-Dimensional Painlevé-Type Equations Associated with Ramified Linear Equations III: Garnier Systems and Fuji-Suzuki Systems

Hiroshi Kawakami

This is the last part of a series of three papers entitled "Four-dimensional Painlevé-type equations associated with ramified linear equations". In this series of papers we aim to…

Regular flat structure and generalized Okubo system

Hiroshi Kawakami, Toshiyuki Mano

We study a relationship between regular flat structures and generalized Okubo systems. We show that the space of variables of isomonodromic deformations of a regular generalized Ok…

Four-dimensional Painlevé-type equations associated with ramified linear equations II: Sasano systems

Hiroshi Kawakami

This is a continuation of the paper "Four-dimensional Painlevé-type equations associated with ramified linear equations I: Matrix Painlevé systems" (arXiv:1608.03927). In this seri…

Four-dimensional Painlevé-type equations associated with ramified linear equations I: Matrix Painlevé systems

Hiroshi Kawakami

As a sequel to Kawakami-Nakamura-Sakai (arXiv:1209.3836), this series of papers constructs the complete degeneration scheme of four-dimensional Painlevé-type equations which includ…

Degeneration scheme of 4-dimensional Painlevé-type equations

Hiroshi Kawakami, Akane Nakamura, Hidetaka Sakai

Four 4-dimensional Painlevé-type equations are obtained by isomonodromic deformation of Fuchsian equations: they are the Garnier system in two variables, the Fuji-Suzuki system, th…
