Mark shared with us his work on a project to describe curves which live on quadric surfaces by a differential equation using only curvature and torsion.
Then we jumped into talking about Christoffel symbols! We discussed several exercises from Shifrin section 2.3: Christine did #1 and #2a. Mark did #4. Emily started to do #2c, but asked for a redo.
Next time, Sladana will share her project with us, and we’ll do more about local geometry of surfaces.
