[HTML][HTML] Hausdorff measure of sets of Dirichlet non-improvable affine forms

T Kim, W Kim - Advances in Mathematics, 2022 - Elsevier
For a decreasing real valued function ψ, a pair (A, b) of a real m× n matrix A and b∈ R m is
said to be ψ-Dirichlet improvable if the system‖ A q+ b− p‖ m< ψ (T) and‖ q‖ n< T has a …

Metrical properties of the large products of partial quotients in continued fractions

B Tan, QL Zhou - Nonlinearity, 2024 - iopscience.iop.org
The study of products of consecutive partial quotients in the continued fraction arises
naturally out of the improvements to Dirichlet's theorem. We study the distribution of the two …
