I'm sorry Benk, it must be me, but I still don't quite get your question. Let's for simplicity drop the whole hyperspace-thing for the moment, and just consider an 'ordinary' 2-sphere embedded in three spatial dimensions (no time). Then, if one lived on the 'flatland' (or more perhaps more...

They're just fancy (short) names for '6-dimensional (hyper-)sphere' and '6-dimensional http://en.wikipedia.org/wiki/Minkowski_space" ', which treats the time-direction as something special (as opposed to 6-dimensional Euclidean spacetime, where all directions - including time - are on an equal...

A single dimension cannot look like something 2-dimensional, such as a sphere or donut - so I suppose you are either referring to 5+1-dimensional spacetime with two spatial dimensions compactified on a sphere, or to the 6 'extra' (compact) dimensions in superstring theory. Anyway, in the first...

I suppose that would just follow from momentum conservation... unless of course there happen to be more than one of those kind of fields involved in a single interaction.

You did it right, and those 4 terms cancel one another. |D_{\mu}\phi|^2 = \frac{1}{2} [(\partial_{\mu} - ieA_{\mu})(v+H)] [(\partial^{\mu} + ieA^{\mu})(v+H)] = \frac{1}{2}[\partial_{\mu}H\partial^{\mu}H + e^2A_{\mu}A^{\mu}(v+H)^2 + ieA^{\mu}(v+H)\partial_{\mu}H - ieA_{\mu}(v+H)\partial^{\mu}H]...

*kick* Hi guys, as I was searching for the solutions of the Zwiebach-book, I stumbled upon this thread. Like the most of you, I've recently begun working through the book by myself, getting stuck at the problems at times. I would really appreciate it if anyone could send the solutions...
