Quasilocal Background Approach to the One-loop Effective Action

Discipline: Mathematics



The one-loop effective action that accommodates an arbitrary number of covariant derivatives of a strong but slowly-varying background field is presented in closed/arm. The internal symmetry and space-time dimension are kept arbitrary in the formalism. The first few terms in the perturbative expansion of the one-loop effective action are derived and are found to agree with those obtained using popular methods.
