abstract

In a small simply-connected closed 4-manifold, we construct infinitely many pairs of exotic codimension-$1$ submanifolds with diffeomorphic complements that remain exotic after any number of stabilizations by $ S^2 \times S^2$. We also give new constructions of exotic embeddings of 3-spheres in 4-manifolds with diffeomorphic complements.

  1. Families of diffeomorphisms, embeddings, and positive scalar curvature metrics via Seiberg-Witten theory

    math.GT 2025-01 accept novelty 7.0 of 10

    A new gluing theorem for parameterized Seiberg-Witten invariants gives infinite rank Z^∞ summands in higher homotopy and homology of diffeomorphism groups of 4-manifolds that are topologically trivial.

  2. Exotic families of embeddings

    math.GT 2025-01 conditional novelty 6.0 of 10

    Smooth embeddings of 3-manifolds in 4-manifolds that are topologically trivial but smoothly exotic, both as individual embeddings and in families parameterized by spheres, are constructed and detected.
