Some Results on Important Inequalities for Univalent Functions with Positive and Negative Coefficients

Abstract

As it is known from Real Analysis, inequalities are used to give the definition of many mathematical concepts formally and to analyze them analytically. Similarly, the geometric characterizations of the range of analytic and univalent functions in the open unit disc U = {z ∈ C : |z| lt; 1} can be easily analyzed with inequalities and easily classified these functions.
