可积性与实意义下的对数有界变差概念（英文）

Integrability and Logarithm Bounded Variation Concept in Real Sense

遵循在均值有界变差概念中取消正性的思想,本文对可积性作出了本质的拓广,并利用实意义下的对数有界变差条件推广了Boas和Heywood的经典定理.

Following the idea to drop positivity in mean value bounded variation concept, this paper gives an essential extension to integrabilty, which generalizes a classical theorem of Boas and Heywood by using logarithm bounded variation condition in real sense.
