Rational Solutions for the Discrete Painlev\'e II Equation
Abstract
The rational solutions for the discrete Painlev\'e II equation are constructed based on the bilinear formalism. It is shown that they are expressed by the determinant whose entries are given by the Laguerre polynomials. Continuous limit to the Devisme polynomial representation of the rational solutions for the Painlev\'e II equation is also discussed.
