Title: Surface diagrams of smooth 4−manifolds

Abstract: Surface diagrams are a relatively new way to depict smooth, closed orientable 4−manifolds using a closed orientable surface decorated with simple closed curves. I will describe them and a few recent results about how well-behaved they are with respect to uniqueness and invariants of 4−manifolds.
