On the solvability of Painlevé II and IV

  • A. S. Fokas
  • Xin Zhou


We introduce a rigorous methodology for studying the Riemann-Hilbert problems associated with certain integrable nonlinear ordinary differential equations. For concreteness we investigate the Painlevé II and Painlevé IV equations. We show that the Cauchy problems for these equations admit in general global, meromorphic int solutions. Furthermore, for special relations among the monodromy data and fort on Stokes lines, these solutions are bounded for finitet.
