Hone, Andrew N.W., Zullo, F. (2018) A Hirota bilinear equation for Painlevé transcendents PIV, PII and PI. Random Matrices: Theory and Applications, 7 (4). Article Number 1840001. ISSN 2010-3263. (doi:10.1142/S2010326318400014) (KAR id:70201)


We present some observations on the tau-function for the fourth Painlev´e equation.

By considering a Hirota bilinear equation of order four for this tau-function,

we describe the general form of the Taylor expansion around an arbitrary movable

zero. The corresponding Taylor series for the tau-functions of the first and

second Painlev´e equations, as well as that for the Weierstrass sigma function,

arise naturally as special cases, by setting certain parameters to zero.
