Determinant Structure of the Rational Solutions for the Painlevé II Equation
Kenji Kajiwara, Yasuhiro Ohta
Abstract
Two types of determinant representations of the rational solutions for the Painlevé II equation are discussed by using the bilinear formalism. One of them is a representation by the Devisme polynomials, and another one is a Hankel determinant representation. They are derived from the determinant solutions of the KP hierarchy and Toda lattice, respectively.
