For f ? ?, operators Dnf with n ? Z = {…,?1, 0, 1,…} are introduced. Applying differential subordinations for analytic functions in the open unit disc U, some interesting properties of f ? ? with Dnf are discussed, and argument problems of Dnf are given. Also, we consider some simple problems for our results.eninfo:eu-repo/semantics/closedAccessAnalytic functionArgument problemDifferential subordinationMeromorphic functionSubordination problems for certain meromorphic functionsSubordination problems for certain meromorphic functionsArticle923003132-s2.0-8517907730010.22034/KJM.2023.393104.2841Q4
