In mathematics, a quasi-isometry is a function between two metric spaces that respects large-scale geometry of these spaces and ignores their small-scale details. Two metric spaces are quasi-isometric if there exists a quasi-isometry between them. The property of being quasi-isometric behaves like an equivalence relation on the class of metric spaces. The concept of quasi-isometry is especially important in geometric group theory, following the work of Gromov.

Property Value
dbo:abstract
  • Der Begriff der Quasi-Isometrie dient in der Mathematik dazu, die „grobe“ globale Geometrie metrischer Räume zu untersuchen. Er spielt in zahlreichen Gebieten der Geometrie, Analysis und geometrischen Gruppentheorie eine wichtige Rolle, etwa in der Theorie der hyperbolischen Gruppen oder in Beweisen von Starrheitssätzen.
