We solve Schrödinger's equation for the ground-state of four-dimensional Yang-Mills theory as an expansion in inverse powers of the coupling. Expectation values computed with the leading-order approximation are reduced to a calculation in two-dimensi...

The consistency of topological expansions in field theory: “BRST anomalies” in strings and Yang-Mills (1994)

Many field theories of physical interest have configuration spaces consisting of disconnected components. Quantum mechanical amplitudes are then expressed as sums over these components. We use the Faddeev-Popov approach to write the terms in this top... Read More about The consistency of topological expansions in field theory: “BRST anomalies” in strings and Yang-Mills.
