On Good $2$ -Query Locally Testable Codes from Sheaves on High Dimensional Expanders

Uriya A. First, Tali Kaufman

We expose a strong connection between good $2$ -query locally testable codes (LTCs) and high dimensional expanders. Here, an LTC is called good if it has constant rate and linear di…

The Cheeger Inequality and Coboundary Expansion: Beyond Constant Coefficients

Uriya A. First, Tali Kaufman

The Cheeger constant of a graph, or equivalently its coboundary expansion, quantifies the expansion of the graph. This notion assumes an implicit choice of a coefficient group, nam…

Azumaya Algebras With Orthogonal Involution Admitting an Improper Isometry

Uriya A. First

Let $(A, σ)$ be an Azumaya algebra with orthogonal involution over a ring $R$ with $2 \in R^{\times}$ . We show that if $(A, σ)$ admits an improper isometry, i.e., an element $a \in A$ wi…
