Kernels of operators on Banach spaces induced by almost disjoint families

Bence Horváth, Niels Jakob Laustsen

Let~ $A$ be an almost disjoint family of subsets of an infinite set~ $Γ$ , and denote by~ $X_{A}$ the closed subspace of~ $ℓ_{\infty} (Γ)$ spanned by the indicator f…

Equivalence after extension and Schur coupling for Fredholm operators on Banach spaces

Sanne ter Horst, Niels Jakob Laustsen

Schur coupling (SC) and equivalence after extension (EAE) are important relations for bounded operators on Banach spaces. It has been known for 30 years that the former implies the…
