%0 Journal Article %T A Problem and A Generalization %A A. Erfanmanesh %J Asian Journal of Fuzzy and Applied Mathematics %D 2016 %X In this work, we generalize a problem in [1].This problem can be used in approximation theory and applied mathematical sciences. Finally, we solve a problem on a null set in a measure space, in a simple way. %K [Metric Space %K Compact set %K Closed set %K Measure space %K Null set] %U https://www.ajouronline.com/index.php/AJFAM/article/view/553
