摘要:The Lacunary Fourier Series  is a well-studied subject with several interesting properties in the classical analysis.  In this talk, I will first review these properties, especially the unconditionality of Lacunary series in the Lp spaces of the unit disc. I will then  explain an open question on the unconditionality of length-lacunary Fourier series on free group C* algebras and discuss the related problems and results.  Part of the talk is based on joint works with Chianyeong  Chuah, Yazhou Han and Zhenchuan  Liu.
