Abstract

In this paper, we introduce the concept of fuzzy semi-weakly r-semicontinuous mappings on a fuzzy topological space and study characterizations for such mappings. And we investigate the relationships among fuzzy r-semicontinuity, fuzzy semi-weakly r-semicontinuity and fuzzy weakly r-semicontinuity.

Fuzzy semi-weakly r-semicontinuous 함수의 개념을 소개하며 특성을 조사한다. 본 논문에서 소개된 함수와 fuzzy r-semicontinuity와 fuzzy weakly r-semicontinuity의 관계를 밝힌다.
