The first part is concerned with the study of ideals in the ring $C^\\infty(M,R)$ of smooth functions on a compact smooth manifold M or more generally submodules of a finitely generated $C^\\infty(M,R)$-module V. We define a topology on the space of all submodules of V of a fixed finite codimension d. Its main property is that it is compact Hausdorff and, in the case of ideals in the ring itself, it contains as a subspace the configuration space of d distinct unordered points in M and therefore gives a \"compactification\" of this configuration space. We present a concrete description of this space for low codimensions. The main focus is then put on the second part which is concerned with a generalization of Vassiliev's h-principle. This principle in its simplest form asserts that the jet prolongation map $j^r:C^\\infty(M,E)\\to\\Gamma(J^r(M,E))$, defined on the space of smooth maps from a compact manifold M to a Euclidean space E and with target the space of smooth sections of the jet bundle $J^r(M,E)$, is a cohomology isomorphism when restricted to certain \"nonsingular\" subsets (these are defined in terms of a certain subset $R\\subseteq J^r(M,E)$). Our generalization then puts this theorem in a more general setting of topological $C^\\infty(M,R)$-modules. As a reward we get a strengthening of this result asserting that all the homotopy fibres have zero homology.", "revisions": [ { "version": "v1", "updated": "2007-05-02T18:02:54.000Z" } ], "analyses": { "subjects": [ "58K60", "53C23" ], "keywords": [ "vassilievs h-principle", "generalization", "configuration space", "jet prolongation map", "compact smooth manifold" ], "tags": [ "dissertation" ], "publication": { "journal": "Ph.D. Thesis", "year": 2007, "month": "May" }, "note": { "typesetting": "TeX", "pages": 91, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2007PhDT........68V" } } }
