Mladineo) -- The grassmannian for piecewise smooth immersions -- Some applications to smoothing theory -- Equivariant piecewise differentiable immersions -- Piecewise differentiable immersions into riemannian manifolds.The book explores the possibility of extending the notions of "Grassmannian" and "Gauss map" to the PL category. They are distinguished from "classifying space" and "classifying map" which are essentially homotopy-theoretic notions. The analogs of Grassmannian and Gauss map defined incorporate geometric and combinatorial information. Principal applications involve characteristic class theory, smoothing theory, and the existence of immersion satifying certain geometric criteria, e.g. curvature conditions. The book assumes knowledge of basic differential topology and bundle theory, including Hirsch-Gromov-Phillips theory, as well as the analogous theories for the PL category. The work should be of interest to mathematicians concerned with geometric topology, PL and PD aspects of differential geometry and the geometry of polyhedra.Lecture Notes in Mathematics,0075-8434 ;1366Differential topologyPiecewise linear topologyGrassmann manifoldsDifferential topology.Piecewise linear topology.Grassmann manifolds.514.34Levitt N(Norman),1943-56520MiAaPQMiAaPQMiAaPQBOOK996466658103316Grassmannians and Gauss maps in piecewise-linear topology80216UNISA
