Corresponding to each (x,y) in the plot of the Pearcey integral is a function of u, f(x,y,u)=∫exp(i(t⁴+xt²+yt))dt where dt is from -∞ to u. f(x,y,.):ℝ->ℂ gives a curve in the complex plane. It's a family of Cornu-like spirals as I drag my mouse around the plot.pic.twitter.com/8McV3aS24q

Is there a known relationship between the Pearcey integral and the Painleve transcendents?
