Geometric function theory is one of the most important branches of complex analysis which deals with the geometric properties of analytic functions. Conformal invariants are frequently used in geometric function theory, especially to investigate plane conformal mapping problems and to study quasiconformal maps in Euclidean n-space. Some of the applications are related to bounds for conformal invariants in terms of certain special functions of classical analysis. The main aim of this special issue is to invite the authors to submit their original research articles as well as review articles that will stimulate the continuing efforts in classical analysis, geometric function theory, and conformal invariants. Potential topics include, but are not limited to:

• Conformal invariants
• Harmonic mappings
• Hyperbolic type metrics
• Potential theory
• Quasiconformal mappings
• Univalent functions
• Special functions and inequalities associated with these topics
