In joint work with Paul Hacking and Sean Keel, we prove a conjecture of Looijenga. Cusp singularities, surface singularities whose minimal resolution is a cycle of rational curves, come in dual pairs. Looijenga’s 1982 conjecture stated that a cusp singularity was smoothable if and only if the dual cusp could be found on a rational surface. We use techniques developed by myself and Siebert to prove this conjecture.
