Exotic 4-manifolds with signature zero – R. Inanç Baykur (University of Massachusetts Amherst)


Aula Seminari - Dipartimento di Matematica


We are going to talk about our recent construction of small symplectic 4-manifolds with signature zero, which include the smallest closed simply-connected exotic 4-manifolds with signature zero known to date. Our novel examples are derived from explicit Lefschetz fibrations, with spin and non-spin monodromies. Joint work with N. Hamada.
