Sharp rational points counting near nondegenerate curves in $R^{n}$

Shengwen Gan, Shaoming Guo, Changkeun Oh

We establish sharp bounds for rational points near compact smooth nondegenerate curves in $R^{n}$ , for every $n \geq 4$ . For a nondegenerate curve $C$ in $R^{n}$ …

Positive measure for restricted projections along smooth non-degenerate curves

Seonghun Jeon, Changkeun Oh

Let $1 \leq m < n$ , and let $γ : [0, 1] \to R^{n}$ be a smooth non-degenerate curve. For $θ \in [0, 1]$ , set \[ V_θ := \operatorname{span} \{γ'(θ),\ldots,γ^{(m)}(θ)\}, \] and let $π_{θ}$ …
