Lie Groups: The Exceptional Lie Group G2

In this lecture, the second of two we are showing from Jason Lotay's fourth year undergraduate course, Jason explains how the smallest exceptional Lie Group is called G2 and has surprising connections to number fields, geometry and physics. This lecture applies much of the general theory of Lie Groups to study this fascinating group.

Third and fourth year lectures are followed by classes.
