Mimi Tsuruga speaks on "What is ... a Killing vector field?" at the "What is ...?" seminar. The talk took place on Friday, April 30, 5pm at the BMS Lounge in TU Berlin.

Abstract

A Killing vector field is a vector field on a Riemannian manifold that preserves the metric. We will go through some basic concepts in differential geometry including Riemannian metric, isometries, and Lie derivatives, and note some nice properties of Killing fields.
