Additionally to the abstract on the paper itself, the following:

Fairly formally, I construct the Lie algebra of globally U(1) invariant observables of the free quantized Dirac spinor field, call it *D*, starting from a commuting raising and lowering algebra, call it *B* (instead of the usual process of starting from an anti-commuting raising and lowering algebra, call it *F*). So we have *D**⊂B* as well as the usual *D**⊂F*. Something of a *surprise* that this is possible, even more that it takes only a few lines in the notation I use, but once that's done the usual vacuum state over *D*, which of course has an extension over *F*, can also be extended to act over *B* (here, trivially), with the resulting state having properties that to me seem striking. The more-or-less classicality that emerges is the least of the transformation of how we can think about fermion fields.

I will mention that the notation I use in the paper might be offputtingly novel, however it has a moderately principled motivation as the use of intrinsic vector methods in the test function space (which for free fields is equipped with a pre-inner product), which I have found and I commend it to you as a very rewarding way to think about quantum field theory.
