Uniform stratified vanishing and equidistribution on $G_{m}^{d}$

Amadou Bah, K. V. Shuddhodan

We prove a uniform stratified generic vanishing theorem for perverse sheaves on $G_{m}^{d}$ over finite fields, with constants depending only on the dimension and on the compl…

Mixels: Fabricating Interfaces using Programmable Magnetic Pixels

Martin Nisser, Yashaswini Makaram, Lucian Covarrubias +4

In this paper, we present Mixels, programmable magnetic pixels that can be rapidly fabricated using an electromagnetic printhead mounted on an off-the-shelve 3-axis CNC machine. Th…

Variation of the Swan conductor of an $F_{ℓ}$ -sheaf on a rigid annulus

Amadou Bah

Let $C = A (r, r^{'})$ be a closed annulus of radii $r$ and $r^{'}$ ( $r < r^{'} \in Q_{\geq 0}$ ) over a complete discrete valuation field with algebraically closed residue field of ch…

Variation of the Swan conductor of an $F_{ℓ}$ -sheaf on a rigid disc

Amadou Bah

This article studies the variation of the Swan conductor of a lisse étale sheaf of $F_{ℓ}$ -modules $F$ on the rigid unit disc $D$ over a complete discrete val…

Phase Transition in the One-bit Johnson-Lindenstrauss Lemma

Amadou Bah, Bryson Kagy, Emily Smith

The Johnson-Lindenstrauss Lemma (J-L Lemma) is a cornerstone of dimension reduction techniques. We study it in the one-bit context, namely we consider the unit sphere $ \mathbb S ^…

A Non-iterative Parallelizable Eigenbasis Algorithm for Johnson Graphs

Jackson Abascal, Amadou Bah, Mario Banuelos +2

We present a new $O (k^{2} (k n)^{2})$ method for generating an orthogonal basis of eigenvectors for the Johnson graph $J (n, k)$ . Unlike standard methods for computing a full eige…
