Estimating the numerical range with a Krylov subspace

Cecilia Chen, John Urschel

Krylov subspace methods are a powerful tool for efficiently solving high-dimensional linear algebra problems. In this work, we study the approximation quality that a Krylov subspac…

On the maximum $F$ -free induced subgraphs in $K_{t}$ -free graphs

JÃ³zsef Balogh, Ce Chen, Haoran Luo

For graphs $F$ and $H$ , let $f_{F, H} (n)$ be the minimum possible size of a maximum $F$ -free induced subgraph in an $n$ -vertex $H$ -free graph. This notion generalizes the Ramsey fun…
