A Problem and A Generalization
Keywords:Metric Space, Compact set, Closed set, Measure space, Null set
In this work, we generalize a problem in .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.
