Global Convergence of Hessenberg Shifted QR I: Exact Arithmetic

Jess Banks, Jorge Garza-Vargas, Nikhil Srivastava

Rapid convergence of the shifted QR algorithm on symmetric matrices was shown more than fifty years ago. Since then, despite significant interest and its practical relevance, an un…

Spectral asymptotics for contracted tensor ensembles

Benson Au, Jorge Garza-Vargas

Let $T_{d, N} : Ω \to R^{N^{d}}$ be a random real symmetric Wigner-type tensor. For unit vectors $(u_{N}^{(i, j)})_{i \in I, j \in [d - 2]} \subset S^{N - 1}$ , we…

Finite Free Cumulants: Multiplicative Convolutions, Genus Expansion and Infinitesimal Distributions

Octavio Arizmendi, Jorge Garza-Vargas, Daniel Perales

Given two polynomials $p (x), q (x)$ of degree $d$ , we give a combinatorial formula for the finite free cumulants of $p (x) ⊠_{d} q (x)$ . We show that this formula admits a topolo…
