Wednesday, August 10, 2022 — 9:30 AM EDT

Talk #1 (9:30am - 10:45am): Amanda Petcu, Department of Pure Mathematics, University of Waterloo

“Isometric Immersion part 4”

This talk will bring an end to our series on isometric immersions. We will define a totally geodesic immersion and a minimal submanifold. To finish we will introduce and prove the three fundamental equations: Gauss' equation, Ricci's equation, and Codazzi's equation.


Talk #2 (11:00am - 12:15pm): Spiro Karigiannis, Department of Pure Mathematics, University of Waterloo

“Some observations about associative 3-planes in R7 and the Lie algebra g2”

I will show that given an associative 3-plane in R7, it determines a Lie subalgebra of so(7) isomorphic to so(3) \oplus so(3). Some possible applications will be discussed.
