The Cartesian product of exact approximation sets

Jing Guo, Mumtaz Hussain, Bixuan Li +1

We determine the Hausdorff and packing dimensions of Cartesian products of one-dimensional exact approximation sets. Our main result establishes the exact-approximation counterpart…

Approximation by uniformly distributed sequences

Gerardo González Robert, Mumtaz Hussain, Nikita Shulga +1

We consider approximation properties of real points by uniformly distributed sequences. Under some assumptions on the approximation functions, we prove a Khintchine-type - di…

A note on limsup sets of annuli

Mumtaz Hussain, Benjamin Ward

We consider the set of points in infinitely many max-norm annuli centred at rational points in . We give Jarník-Besicovitch type theorems for this set in terms of Ha…

Measure theoretic properties of large products of consecutive partial quotients

Adam Brown-Sarre, Gerardo González Robert, Mumtaz Hussain

The theory of uniform approximation of real numbers motivates the study of products of consecutive partial quotients in regular continued fractions. For any non-decreasing positive…

On the Folklore set and Dirichlet spectrum for matrices

Mumtaz Hussain, Johannes Schleischitz, Benjamin Ward

We study the Folklore set of Dirichlet improvable matrices in which are neither singular nor badly approximable. We prove the non-emptiness for all positive…

Complex numbers with a prescribed order of approximation and Zaremba's conjecture

Gerardo González Robert, Mumtaz Hussain, Nikita Shulga

Given with being a positive integer, we can represent any complex number as a power series in with coefficients in . We prove th…
