Abstract: The Eliashberg-Floer-McDuff theorem is a landmark result in symplectic geometry, stating that any Liouville filling of the standard contact sphere (in dimension at least three) must be diffeomorphic to a ball. This series of lectures will explore this theorem from two perspectives: first, by reviewing the diverse and influential proof techniques it has inspired, and second, by examining its wide-ranging applications—including its unexpected role in solving the smooth rectangular peg problem.
