Linear matroid intersection is an important problem in combinatorial optimization. Given two linear matroids over the same ground set, the linear matroid intersection problem asks you to find a common independent set of maximum size. The deep interest in linear matroid intersection is due to the fact that it generalises ... more >>>

We study the limitations of black-box amplification in the quantum complexity class QMA. Amplification is known to boost any inverse-polynomial gap between completeness and soundness to exponentially small error, and a recent result (Jeffery and Witteveen, 2025) shows that completeness can in fact be amplified to be doubly exponentially close ... more >>>

We study the robust local testability of tensor products of two Algebraic-Geometry (AG) codes. In particular, we prove that \textit{constant rate} AG codes are robust locally testable. This significantly generalizes the seminal result of Polishchuk-Spielman [PS24], which proved robust local testability of Reed-Solomon codes. We establish an algebraic-geometric framework ... more >>>
