Abstract

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.
