Gauge Theory (Semi)-Virtual Seminar: Instantons And Handle Decompositions
To participate in this seminar, please register HERE.
We show that there are homology three-spheres for which any bounding definite four-manifold requires lots of handles. The proof uses instanton Floer homology to show that lots of representations on the boundary must extend over the four-manifold. This is joint work with Paolo Aceto, Ali Daemi, Jen Hom, and JungHwan Park.
