In particular, the Poincaré-Hopf index theorem gives rise to the theory of Chern classes, key manifold-invariants in geometry and topology. It is natural to ask what is the ?good? notion of the index of a vector field, and of Chern classes, if the underlying space becomes singular. The question has been explored by several authors resulting in various answers, starting with the pioneering work of M.-H. Schwartz and R. MacPherson. We present these notions in the framework of the obstruction theory and the Chern-Weil theory. The interplay between these two methods is one of the main features of the monograph. 410 0$aLecture Notes in Mathematics,$x0075-8434 ;$v1987 606 $aFunctions of complex variables 606 $aDynamics 606 $aErgodic theory 606 $aManifolds (Mathematics) 606 $aComplex manifolds 606 $aGlobal analysis (Mathematics) 606 $aAlgebraic geometry 606 $aSeveral Complex Variables and Analytic Spaces$3https://scigraph.springernature.com/ontologies/product-market-codes/M12198 606 $aDynamical Systems and Ergodic Theory$3https://scigraph.springernature.com/ontologies/product-market-codes/M1204X 606 $aManifolds and Cell Complexes (incl.
