Integrability, self-duality & exact solutions.

My research concerns the algebraic and geometric structures of integrable systems and their connections with mathematical physics. I focus on Sato theory, Cauchy matrix methods, (anti-)self-dual Yang–Mills equations, and exact soliton solutions.

Research themes

Structures, methods & solutions.

Yang–Mills & integrable hierarchies

I study the connections between (anti-)self-dual Yang–Mills equations and lower-dimensional integrable hierarchies. Current work includes Sato-theoretic constructions, dimensional reductions, and examples related to the Ward conjecture.

Sato-theoretic construction of the ASDYM hierarchy

Cauchy matrices & direct linearization

Cauchy matrix structures and direct linearization provide constructive approaches to Yang–Mills equations and related integrable systems. I am interested in the algebraic structures underlying these methods and the exact solutions they produce.

Direct linearization of the SU(2) ASDYM equation

Solitons & resonance structures

I investigate exact soliton solutions and resonance phenomena in four-dimensional Wess–Zumino–Witten models. Topics include multiple-pole solutions, V-shape solitons, and the relationship between Cauchy matrix methods and binary Darboux transformations.
