Gauge Theory and Topology Seminar: Exotic 4-manifolds with signature zero

Gauge Theory and Topology Seminar, SEMINARS

Speaker:

Inanc Baykur - University of Massachusetts Amherst / Harvard

We will talk about our recent construction of the smallest closed exotic 4-manifolds with signature zero known to date. Our novel examples are derived from fairly special small Lefschetz fibrations we build, with spin and non-spin monodromies. This is joint work with N. Hamada.
