Talk:Pregeometry (physics)

Needs more links

There are essentially no links in this article to the literature that is refered to. In fact, the article is primarily a book report on a single survey paper.

That said, I actually appreciate this article and think it should stay. The reason is that "pre-geometry" is clearly a theme in modern physics.

One could include some work of Gromov under this rubric, where he connects the continuous and the discrete.

As hinted in the present article, there is a lot of graph theory and discrete math that counts as pre-geometry. (The section "Discrete space-time by Hill" is mis-named. It doesn't cover the subject it claims to; it is tiny relative to it. It should really be called "Hill's proposal in rational geometry" or something.)

Looking around, I found further traces:

• "Spinor Geometry", A. Nicolaidis and V. Kiosses, http://arxiv.org/abs/1201.6231, which seems to go in this direction.

• "Finite temperature spinor pregeometry", G. DENARDO and E. SPALLUCCI, http://www.sciencedirect.com/science/article/pii/0370269383910596#

• Many more like these.

• See causal fermion systems which also starts with spinors. Clearly written by just one guy, but if Wikipedia becomes an extended abstract system, maybe it's not such a problem, but could actually be pretty useful.

• See also causal dynamical triangulation and Regge calculus, another form of pre-geometry.

Plus there's plenty under pre-geometry on Google, often referencing Wheeler. To make sense of it, we really need a few good survey papers or books, or one expert.
