We construct infinitely many compact, smooth 4-manifolds which are homotopy equivalent to S2 but do not admit a spine (that is, a piecewise linear embedding of S2 that realizes the homotopy equivalence). This is the remaining case in the existence problem for codimension-2 spines in simply connected manifolds. The obstruction comes from the Heegaard Floer d invariants.Item Open Access Splicing knot complements and bordered Floer homology(Journal für die reine und angewandte Mathematik (Crelles Journal), 2016-01-01) Hedden, M; Levine, ASItem Open Access Strong Heegaard diagrams and strong L–spaces(Algebraic & Geometric Topology, 2016-12-15) Greene, JE; Levine, AS
