摘要:

建立了非阿基米德局部域上的最小二乘法.同时也确定了到非阿基米德局部域上任意给定的多点的距离和最小的点.

关键词: 非阿基米德局部域, 最小二乘法, 离散赋值, 强三角不等式

Abstract:

The least square method for linear equations over non-archimedean local fields is established.The point from which the sumof distances to some given points over non2archimedean local fields is min-imal is also found.

Key words: non-archimedean local fields, least square method, discrete valuation, strong triangular
