演講摘要:
Let k be a global field and L be a finite dimensional 'etale algebra over k.
We consider the norm equation N_{L/k}(x)=c, where c is a nonzero element in k.
Assume that L contains a cyclic extension factor. We give a necessary and sufficient condition for the local-global principle to hold for this norm equation. We will also give several examples in this talk.
