**Abstract**

We apply Shape Theory and Order Theory to spaces of graphs. We concentrate on

small examples which are minimal for exhibiting various nontrivialities.

**Abstract**

We consider the sense in which Dirac brackets are projections of Poisson brackets. In the process, we define a Dirac tensor, a Dirac projector and a Dirac–Jacobi tensor.
