Fix a symbol $$\underline{a}$$ in the mod- $$\ell $$ Milnor K-theory of a field k, and a norm variety X for $$\underline{a}$$ . We show that the ideal generated by $$\underline{a}$$ is the kernel of the K-theory map induced by $$k\subset k(X)$$ and give generators for the annihilator of the ideal. When $$\ell =2$$ , this was done by Orlov, Vishik and Voevodsky.
