Subject: Fwd: AW: WG: Book on Exact Solutions to EH

Thansk for this offer! Much appreciated. I will wait to see what you think about it and if you see any intertesting metrics the charge density and current density can be worked out on Maxima. If you think it is a good book it is easier for me just to order it from Maxima. I am very intersted in working out the laws of electrodynamics from these metrics.
Today I ordered the book from a bookstore. It is not available on amazon in Europe. However it can be ordered from Amazon in US for a special reduced price of $ 60 (used book, but that should not matter). Here it costs about 140 Euro. Myron: if you are interested I can send over the book to you for a while. Horst

I found this book on
www.physicsforums.com/archive/index/php/t-141757.html
There are in fact thousands of exact solutions to EH. The book is:
H. Stephani, D. Kramer, M. MacCallum, C. Noensaelaus and E. Hertl, “Exact Solutions to Einstein’s Field Equations” (Cambridge University Press, 2003, 2nd .ed.) ISBN 0-521-46136-7.
This posting gives two new metrics, the Friedmann dust solution and a perfect fluid sphere which I will send out next. The exact solutions to EH will ALL give Coulomb and Ampere Maxwell Laws, so a whole book can be built up on this topic, giving thousands of new electrodynamical solutions. This could be published by Abramis as a tabular reference book. I think that the whole book could be produced automatically by Maxima, for example by Horst Eckardt, Tom Widlar, and myself, with commentary by Stephen Crothers. The main classes of exact EH solutions are:
1) Lambda vacua; 2) Dusts; 3) Goedel dust; 4) Perfect fluids; 5) Null dusts; 6) Scalar field solutions; 7) Non-null electrovacua;
Null electrovacua.
Some of these are more important for ECE than others, and many should be subjected to scrutiny by MAxiam to see if they are true EH solutions adn obey the Ricci cylcc equation, and in view of Crothers’ advances and caveats, but this book is well worth consulting by lending library or library. Some solutions conflict with the basic philosophy of ECE, but there are no doubt many that are valid for ECE.
