摘要
本文进一步研究无穷个无穷小量的乘积问题。给出可数个无穷小量之积仍为无穷小量的充分必要条件,并提供了两个简便方法用于判断可数个无穷小数列之积是否仍为无穷小数列。
In this paper, We study deepigy problem about the infinite product of the infinite infinitesimal. On the numerable infinite product of infinitesimal be infintesimal or not, we give a hecessarg and sufficient condition and provide two simple methods to judge it.
