Extremal numbers and multi-parametric geometry of numbers

Damien Roy

We study weighted simultaneous rational approximation to points of the form $(1, I^¾, I^¾^{2})$ , for a class of extremal real numbers $I^¾$ , within the framework of multi-parametric geome…

Best versus uniform Diophantine approximatio

Martin Rivard-Cooke, Damien Roy

Let $0 < m < n$ be integers, and let $K_{w}$ denote the completion of a number field $K$ at a non-trivial place $w$ . For each non-zero $u \in K_{w}^{n}$ , let $I ¨ _{m - 1} (u)$ d…
