Certain Subclasses of Analytic Functions Associated with Generalized Telephone Numbers
The goal of this article is to contemplate coefficient estimates for a new class of analytic functions <i>f</i> associated with generalized telephone numbers to originate certain initial Taylor coefficient estimates and Fekete–Szegö inequality for <i>f</i> in the new function...
