We discuss three open problems in operator and function theory: Crouzeix’s conjecture, Sendov’s conjecture, and the invariant subspace problem. We include the full conjecture, prior work, and related questions.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
