Many people in algebraic geometry know that there are 12 different ways
to pass a rational cubic through 8 points in the plane. It is not as
well-known that if the 8 points are real, then at least 8 of the 12
solutions to this interpolation problem are real. This is part of an
unfolding story that ties together many recent developments in real
algebraic geometry, including Enumerative Real Algebraic Geometry,
Tropical Geometry, and Applications. In my talk (which does not assume
you knew the problem of the first sentence) I will present this intriguing story.
Refreshments will be served at the PIMS Facility prior to the colloquium.
