In this talk I will give a broad overview of my thesis results. The story begins with an attempt to understand an open symplectic surface by retracting it to a trivalent graph. After giving the geometric motivation for this procedure with some examples, I'll explain how to turn this trivalent graph into a homotopy limit of differential-graded categories. From there, we'll discuss the general idea behind homotopy-invariant constructions, giving concrete examples from topology. Then we'll put all of this together to describe why our homotopy limit of categories is an invariant of the original symplectic surface.
