Calabi-Yau threefolds with vanishing third Betti number

Tuesday, April 28, 2009 -
4:30pm to 6:30pm
Smooth, projective, three dimensional, algebraic varieties with trivial canonical sheaf and vanishing third etale Betti number do not exist over fields of characteristic zero. In the past few years a number of examples have been found in positive characteristic. Some of these examples and questions they raise will be discussed.
