线性无缘Galois扩张的多重性原理
The Multinorm Principle For Linearly Disjoint Galois Extensions
摘要:
设L_1和L_2是整体域K的有限可分扩张,E_i是L_i在K上的Galois闭包,其中i= 1,2.在扩张E_1和E_2在K上线性无缘的条件下,我们建立了L_1和L_2范数乘积的局部-整体原理(所谓的多项式原理)。
英文摘要:
Let L_1 and L_2 be finite separable extensions of a global field K, and let E_i be the Galois closure of L_i over K for i=1,2. We establish a local-global principle for the product of norms from L_1 and L_2 (so-called multinorm principle) provided that the extensions E_1 and E_2 are linearly disjoint over K.
