SUMMARY:How Efficiently Do 3-Manifolds Bound 4-Manifolds?
DESCRIPTION:Speaker: How Efficiently Do 3-Manifolds Bound 4-Manifolds?\n\nIt is known since 1954 that every 3-manifold bounds a 4-manifold. Thus, for instance, every 3-manifold has a surgery diagram. There are many proofs of this fact, including several constructive ones, but they do not bound the complexity of the 4-manifold. (By "complexity" of a manifold we mean the …
