Trivializing 5-dimensional h-cobordisms by stabilization

  • Terry Lawson


It is shown that if (W5,M,M′) is an h-cobordism, then the stabilization of W formed by taking boundary connected sum with enough copies of S2×D3 is diffeomorphic to the boundary connected sum of M×I with these copies of S2×D3. When M is bounded, stabilization leads to a product structure. A key step is a proof of the stabilized 5-dimensional s-cobordism conjecture.
