Rational subvarieties in positive characteristic
October 24 to October 28, 2016
American Institute of Mathematics,
San Jose, California
and Matthew Woolf
This workshop will be devoted to studying
rationality and existence of rational subvarieties in positive characteristic.
Positive characteristic algebraic geometry provides additional tools, such as
the Frobenius morphism, as well as challenges, such as the failure of generic
smoothness. This workshop will bring together experts in both characteristic 0
and characteristic p to study questions related to rational varieties such as
- When do the rational subvarieties of a Fano manifold, resp. general type
variety, behave as expected from complex geometry?
- Which varieties of nonnegative Kodaira dimension are unirational, and what
can we say about the moduli of these unirational varieties?
- How can we exploit positive characteristic methods to prove irrationality
results, especially those results that lift to characteristic 0?
