A Lê number addendum to the Morse Splitting Lemma
David B. Massey
We investigate how the complex analytic Morse Splitting Lemma relates to the generic Lê numbers of a function, and what the relation tells us about the function. As special cases,…
A lower bound on the top Betti number of the Milnor fiber
David Massey
We derive a lower bound for the top possibly-non-zero Betti number of the Milnor fiber of an analytic function in terms of the zero-dimensional Lê number and the internal monodromy…
Verdier dualizing and the variation map
David B. Massey
We describe how the canonical and variation maps between the shifted nearby and vanishing cycles interact with Verdier dualizing.
A Lemma of Lazarsfeld and the Jacobian blow up
David B. Massey
For a complex analytic function , the exceptional divisor of the jacobian blow-up is of great importance. In this paper, we show what a lemma from the thesis of Lazarsfeld tells…
A Non-isolated Addendum to the Theorem of Bobadilla and Pełka
David B. Massey
We show that the Theorem of Bobadilla and Pełka implies a non-isolated version for aligned hyper surface singularities.
A note on the support and cosupport conditions for a perverse sheaf
David B. Massey
We give a characterization of the support and cosupport conditions for a perverse sheaf in terms of the Whitney filtration.
