In studying general relativity I have calculated all the Christoffel
symbols, Riemann and Einstein curvatures for the Schwarzschild, spherically
symmetric and FRW geometries from Appendix B (pp546-548) of James Hartle's
Gravitation text.

I obtain agreement everywhere except for one component of the orthonormal
Riemann curvature for the spherically symmetric geometry:

R_(theta, phi, theta, phi) = (e^-lambda - 1)/r^2 (page 547)

I obtain the opposite sign. I feel fairly confident that this is an error.

I checked the errata for the book from the publisher and did not find it
listed. I don't know how to enquire of Hartle and I couldn't find any email
contact from Addison Wesley.

Has anyone else come across this as an error, or could anyone check it for
me?

Why don't you send an email to Hartle with the same question?

John Anderson

I would if I could find an email address for him. I looked at his home web
page and he gave no email address.

I finally was able to contact James Hartle and he confirms that it is an
errata.
