Positive measure for restricted projections along smooth non-degenerate curves

Seonghun Jeon, Changkeun Oh

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