The matrix-vector complexity of $Ax=b$

arXiv:2602.04842v2 Announce Type: replace-cross Abstract: Matrix--vector algorithms, particularly Krylov subspace methods, are widely viewed as the most effective algorithms for solving large systems of linear equations. This paper establishes lower bounds on the worst-case nu...
