A Little Microlocal Morse Theory
arXiv:math/0006185
Abstract
If a complex analytic function, , has a stratified isolated critical point, then it is known that the cohomology of the Milnor fibre of 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 have isolated support. We also investigate an index-theoretic proof of this fact.
