Quantization of Donaldson-Uhlenbeck-Yau theory

Understand

A covariant path-integral quantization is proposed for the non-Lagrangian gauge theory described by the Donaldson-Uhlenbeck-Yau equation.

• The corresponding partition function is shown to admit a nice path-integral representation in terms of the gauged G/G K\"ahler WZW model.
• A relationship with the $J$-formulation of the anti-self-dual Yang-Mills theory is explored.
