Abstract
If A • is a bounded, constructible complex of sheaves on a complex analytic space X, and \({f : X \rightarrow \mathbb{C}}\) and \({g : X \rightarrow \mathbb{C}}\) are complex analytic functions, then the iterated vanishing cycles φ g [−1](φ f [−1]A •) are important for a number of reasons. We give a formula for the stalk cohomology H*(φ g [−1]φ f [−1]A •) x in terms of relative polar curves, algebra, and Morse modules of A •.
