Welcome to this seminar held by Inanc Baykur with title "Exotic 4-manifolds with signature zero".

Abstract: 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.
