Le Cycles and Hypersurface Singularities [Paperback]

This book describes and gives applications of an important new tool in the study of complex analytic hypersurface singularities: the L? cycles of the hypersurface. The L? cycles and their multiplicities - the L? numbers - provide effectively calculable data which generalizes the Milnor number of an isolated singularity to the case of singularities of arbitrary dimension. The L? numbers control many topological and geometric properties of such non-isolated hypersurface singularities. This book is intended for graduate students and researchers interested in complex analytic singularities.Definitions and basic properties.- Elementary examples.- A handle decomposition of the milnor fibre.- Generalized L?-Iomdine formulas.- L? numbers and hyperplane arrangements.- Thoms a f condition.- Aligned singularities.- Suspending singularities.- Constancy of the Milnor fibrations.- Other characterizations of the L? cycles.Springer Book ArchivesDE
