Abstract:

We outline a strategy for using microlocal sheaf categories to distinguish smooth structures on the same underlying topological four-manifold. Briefly, our strategy is the following: if X is a Stein manifold satisfying certain conditions then we can understand the effect of performing a logarithmic transformation in terms of its Lagrangian skeleton.
