Forthe function ??(??) = ?? + ???????? + ????????+. .. which is defined in the unit disc ?? such that the function ??(??)belongs to the class ??(??), we estimate from below the modulus of the angular derivative of the function????'(??)??(??)at the boundary point ?? with ????'(??)??(??)=????????. Moreover, we get the Schwarz Lemma for the class ??(??).We also investigate some inequalities obtained in terms of sharpness.eninfo:eu-repo/semantics/openAccessSome remarks for a certain class of holomorphic functions at the boundary of the unit discArticle452344631364023
