实二次函数域基本单位的范

On the Norms of Fundermental Units in Real Quadratic Function Fields

研究了实二次函数域基本单位的范．给出了一些范等于ｇ的充分必要条件，并利用图论的语言，给出了一些充分条件．

Some sufficient and necessary conditions of the norms of fundermental units in real quadratic function fields was given. Meanwhile,some sufficient conditions about norms was established by the language of graph theory.
