Large Weyl sums and Hausdorff dimension

Roger C. Baker, Changhao Chen, Igor E. Shparlinski

We obtain the exact value of the Hausdorff dimension of the set of coefficients of Gauss sums which for a given achieve the order at least for infinitely many…

Bounds on the Norms of Maximal Operators on Weyl Sums

Roger C. Baker, Changhao Chen, Igor E. Shparlinski

We obtain new estimates on the maximal operator applied to the Weyl sums. We also consider the quadratic case (that is, Gauss sums) in more details. In wide ranges of parameters ou…

Self-similar sets with super-exponential close cylinders

Changhao Chen

S. Baker (2019), B. Bárány and A. Käenmäki (2019) independently showed that there exist iterated function systems without exact overlaps and there are super-exponentially close cyl…

Metric theory of lower bounds on Weyl sums

Changhao Chen, Bryce Kerr, Igor Shparlinski

We prove that the Hausdorff dimension of the set , such that $$ \left|\sum_{n=1}^N \exp\left(2 πi\left(x_1n+\ldots+x_d n^d\right)\right) \right|\ge c N^{1/2}…

Hybrid bounds on two-parametric family Weyl sums along smooth curves

Changhao Chen, Igor E. Shparlinski

We obtain a new bound on Weyl sums with degree polynomials of the form , , with fixed and , which…

Restricted mean value theorems and metric theory of restricted Weyl sums

Changhao Chen, Igor E. Shparlinski

We study an apparently new question about the behaviour of Weyl sums on a subset with a natural measure on . For certain measure spa…
