The Subrings and Subring Lattice of Rational Field;
有理数域的子环和子环格
This short note is devoted to a new construction of the generalized Vitali s nonmeasurable sets on the real line R,that is,replacing the rationals to arbitray infinitely enumerable subring of R.
将构造实数直线R上的Lebesgue不可测集的Vitali方法推广到R的可数子环,证明了R的不与Z同构的可数子环均在R中稠密,进而证明了相应于可数子环H的广义Vitali集是不可测集当且仅当H不含于整数环Z;证明了广义Vitali不可测集的内测度均是0,而外测度可以是任意正数。
Z(i) is a domain of integrity,this paper gives a way on forming a subring over Z(i);and explicates a class of divisible element s structure.
Z(i)是个整环,文章通过类似二次域上构筑理想的方法构筑Z(i)上的子环,进而明确该子环上的一些可分解元的形式。
