Holmstrom Tame symbol

Redirected from "minimal KS-extension".
Note: minimal dg-module and minimal dg-module both redirect for "minimal KS-extension".

Constructed by Tate. Takes two meromorphic functions on a Riemann surface and associates something at a point x. This satisfies a product formula. See Serre: Algebraic groups and classfields. Also generalizations by Deligne in IHES paper: Le symbole modere, 1991.
