Let Ω ≤ GLd(q) be a quasisimple classical group in its natural representation and let ∆ = NGLd(q)(Ω). We construct the projection from ∆ to ∆/Ω and provide fast, poly...

Let f ∈ Fq[x] be a polynomial of degree d ≤ q/2. It is well-known that f can be uniquely recovered from its values at some 2d points even after some small fraction of the valu...

We propose a framework for compressive sensing of images with local geometric features. Specifically, let x ∈ RN be an N-pixel image, where each pixel p has value xp. The image...
