Using the differentiations and integrations, new operator D-n f (z) is introduced for f (z) is an element of Sigma. The object of the present paper is to discuss some interesting properties for D-n f (z) and some properties concerned with different boundary points of the open unit disk. Moreover, some simple examples for our results are shown.eninfo:eu-repo/semantics/openAccessAnalytic FunctionMeromorphic FunctionDifferential OperatorArticle1012WOS:0009206146000012-s2.0-8513216031010.3390/math10121985Q1Q1
