Abstract
The Clarkson-McLeod solutions of the fourth Painlevé equation behave like as , where is some real constant and is the parabolic cylinder function. Using the Deift-Zhou nonlinear steepest descent method, we derive the asymptotic behaviors for this class of solutions as . This completes a proof of Clarkson and McLeod's conjecture on the asymptotics of this family of solutions. The total integrals of the Clarkson-McLeod solutions and the asymptotic approximations of the -form of this family of solutions are also derived. Furthermore, we find a determinantal representation of the -form of the Clarkson-McLeod solutions via an integrable operator with the parabolic cylinder kernel.
