Specify the gauge group, its gauge group representations and gaugings, a real Kähler potential $K$, a holomorphic superpotential $W$, and a symmetric holomorphic gauge kinetic function $f_{ab}$, with positive kinetic matrices. The latter includes the gauge couplings and theta angles; allowed Abelian Fayet–Iliopoulos terms require constants ${\xi }_a$. For local supersymmetry, also specify the Planck mass; constant Fayet–Iliopoulos terms in conventional N=1 supergravity require a compatible gauged R-symmetry and transformation of $W$. $W$ and $f$ are holomorphic; $K$ generally is not. Radiative corrections generally change $K$. The Wilsonian effective action obeys superpotential non-renormalization perturbatively, although physical couplings run through field normalization and nonperturbative corrections can change $W$. The gauge kinetic function does receive corrections while remaining holomorphic; its perturbative Wilsonian running has one-loop exactness of the holomorphic gauge kinetic function, not all-order constancy of the physical gauge coupling.
