講 題:The local-global principle for multinorm equations
時 間:2020年2月17日 (星期一) 14:00 - 15:00
地 點:臺灣大學天數館
440 室摘 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.
