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| < 1} can be easily analyzed with inequalities and easily classified these functions.

Reel analizden bilindiği gibi, eşitsizlikler birçok matematiksel kavramın tanımını formal olarak vermek ve onları analitik olarak analiz etmek için kullanılır. Benzer olarak birim açık disk U = {z ∈ C : |z| < 1} da analitik ve univalent olan geometrik fonksiyonların görüntü kümeleri eşitsizliklerle kolayca analiz edilebilir ve kolayca bu fonksiyonlar sınıflandırılabilir.
