A short note on simplicial stratifications

Abstract

We show that the simplicial stratification associated to a triangulation of a PL pseudomanifold possesses a canonical system of trivializations of link bundles that satisfies a natural compatibility condition over nested singular strata. Consequently, Agustín Vicente and Fernández de Bobadilla’s generalization of Banagl’s intersection space construction is applicable to all PL pseudomanifolds (and in particular, to all complex algebraic varieties).
