Title:
Associative submanifolds of the Berger space

Speaker:
Gavin Ball

Abstract:
I will describe work (joint with Jesse Madnick) on the study of associative submanifolds of the Berger space SO(5)/SO(3) endowed with its homogeneous nearly parallel G2-structure. I will focus on two different classes of associative submanifold: the ruled associative submanifolds (where the ruling curves are a special type of homogeneous circle), and the associative submanifolds with special Gauss map (meaning that the tangent space has a larger-than-usual SO(3)-stabiliser). Study of the former class results in a construction of infinitely many diffeomorphism types of immersed ruled associative submanifolds.
