Tóm tắt

The author's recent results on an asymptotic description of the Schlesinger equation are generalized to the Jimbo–Miwa–Môri–Sato (JMMS) equation. As in the case of the Schlesinger equation, the JMMS equation is reformulated to include a small parameter ε. By the method of multi-scale analysis, the isomonodromic problem is approximated by slow modulations of an isospectral problem. A modulation equation of this slow dynamics is proposed and shown to possess a number of properties similar to the Seiberg–Witten solutions of low energy supersymmetric gauge theories.
