Research Field :
Theory of lacunary series, Uniform distribution theory, and Probability theory


Research Summary :
Randomness appears in many forms among researches on lacunary series and uniform distribution theory of numbers. We focus on stochastic properties of lacunary sequences, especially geometric progression, and prove metric discrepancy results.
