基于粗糙Cauchy数列,研究粗糙数项级数及其粗糙收敛性质。定义粗糙数项级数的粗糙敛散性,确立粗糙和的离散度量唯一性与连续实值不唯一性,得到数项级数的粗糙收敛与精确收敛的转化关系与性质差异。相关研究推进粗糙数列到粗糙数项级数。
This paper utilizes rough Cauchy sequences to investigate rough numerical series and their properties.Rough numerical series are defined to demine their rough convergence and divergency,both measure-based uniqueness and realvalued nonuniqueness of rough sums are established,and transformation relationships and property differences between rough and precise convergence of numerical series are achieved.This relevant study promotes rough sequences to rough numerical series.
