Differential topology : proceedings of the Second Topology Symposium held in Siegen, FRG, Jul. 27Aug. 1, 1987 by
U Koschorke(
Book
)
22 editions published in 1988 in English and held by 369 WorldCat member libraries worldwide
The main subjects of the Siegen Topology Symposium are reflected in this collection of 16 research and expository papers. They center around differential topology and, more specifically, around linking phenomena in 3, 4 and higher dimensions, tangent fields, immersions and other vector bundle morphisms. Manifold categories, Ktheory and group actions are also discussed

Cobordismes d'immersions lagrangiennes et legendriennes by
Michèle Audin(
Book
)
1 edition published in 1986 in French and held by 4 WorldCat member libraries worldwide
We compute V .I. Arnold's cobordism groups of Lagrange immersions in the cotangent bundle of a manifold : we deduce them from the special case of the cotangent bundle of IRn , those groups are the cobordism groups of manifold whose tangent bundle, when complexified, is trivialized ; we study in detail the algebraic invariants related to that situation, and give applications to the enumerative theory of Lagrange singularities. We use these results to compute the Cobordism groups of Legendre immersions in some contact elements manifolds. Methods use many aspects of cobordism theory and results can be used to show the existence of Lagrange or Legendre immersions satisfying certain conditions although very few explicit examples are known
