Cancellation properties of exotic 4-dimensional positive scalar curvature metrics
Johannes Ebert (Münster)
It is well-known that 4-dimensional smooth topology offers many exotic phenomena, typically detected by means of gauge theory, and it is also well-known
that these exoticities are very unstable when...
