Inertia stack
In mathematics, especially in differential and algebraic geometries, an inertia stack of a groupoid X is a stack that parametrizes automorphism groups on X and transitions between them. It is commonly denoted as \Lambda X and is defined as inertia groupoids as charts. The notion often appears in particular as an inertia orbifold.
