A Little Microlocal Morse Theory

Algebraic Geometry 2007-05-23 v2

Abstract

If a complex analytic function, ff, has a stratified isolated critical point, then it is known that the cohomology of the Milnor fibre of ff has a direct sum decomposition in terms of the normal Morse data to the strata. We use microlocal Morse theory to obtain the same result under the weakened hypothesis that the vanishing cycles along ff have isolated support. We also investigate an index-theoretic proof of this fact.
