Quantitative Khintchine on the parabola with non-monotonic approximation functions
Maiken Gravgaard, Simon Kristensen
We prove a quantitative version of the convergence case of Khintchine's celebrated theorem in metric Diophantine approximation, but where the approximated points are restricted to…

Decomposition of real numbers into sums of Lüroth sets
Maiken Gravgaard, Ying Wai Lee
We study the decomposition of real numbers into sums of Lüroth sets, which are defined by numbers whose Lüroth expansions have prescribed digit constraints. We establish several…
