报告摘要: The aim of this lecture is to address many recent conjectures on the family of K-quasiconformal harmonic univalent mappings that are sense-preserving and univalent in the unit disk centered at the origin with radius 1. Also, we consider an affirmative answer in support of the recent coefficient conjecture by proving this conjecture for certain geometric subfamilies which is expected to motivate many studies on geometric function theory. In addition, we verify this conjecture also for on the family of typically real K-quasiconformal harmonic mappings. and provide sharp coefficients estimate of convex K-quasiconformal harmonic mappings. By doing so, the lecture will provide an affirmative document in support of the main coefficient conjecture on the family of K-quasiconformal harmonic univalent mappings .
