There's only so much you can do. The past week was awful, I cant even count the number of times I asked a poster to post MORE information. I try to ignore :).

it's a much needed criticism of the string theorists and how they are sucking up scarce resources from physics research budgets with what I would call "mathematical philosophy". it's not science.

http://adsabs.harvard.edu/abs/2001hep.th...10009A Pseudo-Cuntz Algebra and Recursive FP Ghost System in String Theory "Representation of the algebra of FP (anti)ghosts in string theory is studied by generalizing the recursive fermion system in the Cuntz algebra constructed previously. For that purpose, the pseudo-Cuntz algebra, which is a *-algebra generalizing the Cuntz algebra and acting on indefinite-metric vector spaces, is introduced. The algebra of FP (anti)ghosts in string theory is embedded into the pseudo-Cuntz algebra recursively in two different ways. Restricting a certain permutation representation of the pseudo-Cuntz algebra, representations of these two recursive FP ghost systems are obtained. With respect to the zero-mode operators of FP (anti)ghosts, it is shown that one corresponds to the four-dimensional representation found recently by one of the present authors (M. Abe) and Nakanishi, while the other corresponds to the two-dimensional one by Kato and Ogawa."

"Pseudo-Cuntz Algebra" is either 2-dimensional or 4-dimensional.

Yeah, I got the 2-dimensional version , like every one else, off the top-shelf in the newsagent when I was in Junior school, and now you are offering 4-dimensional - when I'm sure my imagination only needs the 3-dimensional version!

seriously, that abstract is a great example of how the string theorists have gone off the deep end. Not a word of it makes sense to me, and I am a (former) physicist!

i'll venture a guess that "zero-mode" means "ground state". so a zero mode operators would be operators that create and destroy particles in their ground states. just a guess.
