We present several new results for higher-order (fourth-order) differential subordination and superordination in this paper by using the new operator Hα,β,𝛿,𝜉,γ,nf(v) and offer numerous new findings for fourth-order differential subordination and superordination The innovative discoveries presented here are connected to those mentioned in previous articles. The differential subordination theory’s characteristics and outcomes are symmetric to the properties gained. Sandwich-type theorems are created by merging differential superordination theory with sandwich-type theorems.
Th goal of the pr s nt p p r is to obt in some differ tial sub rdin tion an sup r dination the rems for univalent functions related b differential operator Also, we discussed some sandwich-type results.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
