Palatini identity

In general relativity and tensor calculus, the Palatini identity is: where denotes the variation of Christoffel symbols and indicates covariant differentiation. A proof can be found in the entry Einstein–Hilbert action. The "same" identity holds for the Lie derivative . In fact, one has: where denotes any vector field on the spacetime manifold .

Carlo Rovelli: The essential role of coherent states in quantum gravity

Abstract: Conventional quantum field theory techniques do not work for extracting physical information from a background-independent quantum theory of gravity. A technique that works is Oeckl's boundary formalism, with semiclassical coherent states on the boundary. I illustrate how this te

Trig identities - What are they?

► My Trigonometry course: https://www.kristakingmath.com/trigonometry-course Trig identities are pretty tough for most people, because 1) there are so many of them, and 2) they’re hard to remember, and 3) it’s tough to recognize when you’re supposed to use them! But don’t worry, because
