Fekete-Szegö Problem for Certain Classes of Analytic Functions Associated with Petal Type Domain and Modified Sigmoid Function
In this work, the authors studied the Fekete-Szegö problems for certain classes of analytic functions associated with petal type domain and modified sigmoid function. The initial coefficient bounds have been obtained and discussed the relevant connection to Fekete-Szegö inequalities. The results give birth to some corollaries.
