Duality in the low dimensional field theory

A strong-weak coupling duality appears in the quantum mechanical many body system with the interacting potential proportional to the pair-wise inverse-squared distance. In the large N limit the field theory formulation possess the soliton solution in non-perturbative Bogomolny-Prasad-Sommerfeld limit (BPS). In this limit we establish duality between original and soliton fields and the dual relation among coupling constants.
