The Fukaya category is an algebraic invariant of symplectic manifolds, where Lagrangian submanifolds are objects, and their intersections are morphisms; Seidel adapted this category to symplectic Lefschetz fibrations. Mirror symmetry connects the symplectic geometry of one manifold to the complex geometry of its mirror. We will outline how a blow-up of a complex manifold along a submanifold is mirror to wrapping of Lagrangians around a puncture on the symplectic side. This is joint work with Sara Venkatesh.
