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 $π_{θ}$ …

Changkeun Oh

We obtain a sharp bilinear restriction estimate for the paraboloid in $R^{3}$ for $q > 3.25$ .
