Why was delta set to 0?

http://en.wikipedia.org/wiki/Formulation_of_Maxwell%27s_equations_in_special_relativity#Maxwell.27s_equations Why does 0 = \epsilon^{\alpha \beta \gamma \delta} \frac{\partial F_{\alpha \beta}}{\partial x^\gamma} reduce to 0 = {\partial F_{\alpha\beta}\over\partial x^\gamma} +...

Hi, Thanks, yes that is what I also did. The "parametric induction" term threw me off.

http://en.wikipedia.org/wiki/Baker-Campbell-Hausdorff_formula#The_Hadamard_lemma I am interested as to how one shows the relation holds when computing s = 1. Any thoughts?

Homework Statement I have to calculate the expected value of the Hamilton operator (average energy) of a two, non interacting, identical particle system. Thus these particles can be bosons or fermions, but at the moment I just want to look at fermions. Homework Equations...

I decided to 1st try and model a white dwarf. My problem is that I can't find a good starting pressure to use. Also, can I assume uniform density for a white dwarf? Does the EoS (polytrope) give me central pressure when a value of rho is inserted into it? Thanks, Karl

Hey, not yet. I am trying to avoid buying a book at the moment because getting them to South Africa is a bit expensive.

Does anyone know of a good reference regarding solving the Tolman-Oppenheimer-Volkov equations for neutron stars? Most things I find are either too elementary and others skip multiple steps. I think the EoS to use should be that of a Fermi gas model, but I am not sure.
