Lie Theory

Riemannian and esp. hyperbolic geometry in Sarnak course... e.g. Laplacian of hyperbolic spaces used early.

Terry Tao 285G, Lecture 0: Riemannian manifolds and curvature... want to be less scared of this.

Tao: What is a gauge?

MO: one-parameter subgroup and geodesics on Lie group

Tao: geodesic flow and Euler-Arnold equation

Maximum number of Killing vectors (google it... mentioned in Dafermos course Fall 2017)

MO: sheaves and bundles in differential geometry

References from Mohan... John Pardon: algebraic approach to virtual fundamental cycles on moduli spaces of pseudo-holomorphic curves. McDuff Salamon. Gromov Chris Wendl (nonsqueezing theorem notes)?

Special values of L-functions and hyperbolic manifolds. Zagier paper (Google it)?

Why are all knots trivial in 4D? (MSE?)

Jacobi identity intuitive explanation: MSE... intuitively, differentiate $g_th_txh_t^{-1}g_t^{-1}$ in two different ways?

Wick rotation in physics (Minkowski vs Euclidean space)... Wayne.
