Counterexamples to the Local-To-Global Principle for Rational Points in Low Dimension

Speaker: Alexei Skorobogatov, Imperial College, London

Location: Warren Weaver Hall 1314

Date: Tuesday, October 6, 2015, 3:30 p.m.

Synopsis:

I will describe elementary counterexamples to the Hasse principle in dimension 2 and 3 that are not detected by known obstructions. One of them is a conic bundle over an elliptic curve over a real quadratic field.
