For functions on the real line, the Henstock integral is an even more general notion of integral (based on Riemann's theory rather than Lebesgue's) that subsumes both Lebesgue integration and improper Riemann integration.
Henstockintegralet er et endnu mere generelt integralbegreb, (der er baseret på Riemanns teori snarere end Lebesgues,) som subsumerer både Lebesgueintegration og uegentlig Riemannintegration.
