Abstract

One of the fundamental parts of Geometric Function Theory is the study of analytic functions in different domains with critical geometrical interpretations. This article defines a new generalized domain obtained based on the quotient of two analytic functions. We derive various properties of the new class of normalized analytic functions (Formula presented.) defined in the new domain, including the sharp estimates for the coefficients (Formula presented.), and (Formula presented.), and for three second-order and third-order Hankel determinants, (Formula presented.), and (Formula presented.). The optimality of each obtained estimate is given as well.
