On the asymptotic analysis of the Painlevé equations via the isomonodromy method

TL;DR: In this article, the problem of the rigorous justification of the global asymptotic results obtained via the Isomonodromy Method is considered, taking the pure imaginary solutions of the second Painleve equation as an example.
