DESCRIPTION:.... Date\n\nThursday, May 23, 2019 - 13:00 to 14:00 .... Des
cription\n\nAbstract: It is known that there exist many 'non-smoothable 4-
manifolds', that is, topological 4-manifolds which do not admit smooth
manifold structures. Gauge theory provides a strong tool to detect such i
nteresting topological 4-manifolds. In this talk, I will explain a famil
y version of this story. Namely, I will show that a family version of ga
uge theory may detect 'non-smoothable 4-manifold bundles', which is a fi
ber bundle whose structure group is the homeomorphism group of a 4-manifo
ld, but we cannot reduce the structure group into the diffeomorphism gro
up. This is joint work with David Baraglia and with Tsuyoshi Kato and Nob
uhiro Nakamura.
