+**Abstract:** One of the most surprising discoveries in 4-manifold topology was the existence of smooth manifolds homeomorphic, but not diffeomorphic, to Euclidean 4-space. For fundamental reasons, this phenomenon can only occur in 4 dimensions. We will survey the subject, from its origin to recent developments regarding symmetries of such manifolds.
+The lecture will be followed by a reception at 4:15 p.m. in The President's Reception Room, [[https://www.google.com/maps/place/Anderson+Center+For+the+Arts/@42.089995,-75.9712084,17z/data=!3m1!4b1!4m2!3m1!1s0x89daeec655555555:0x9087c02e1a55a797|Anderson Performing Arts Center]], Binghamton University. This reception is for the whole Binghamton Mathematics Community as well as for our visitors.
