• “This then leads us into some very rich theory of the algebraic topology of the Dirac operator and something called quantum cohomology.”

  Dark Matter: Still Dark.

• “BRST then becomes essentially Lie algebra cohomology, where you construct the invariant, trivial piece of a representation by cancelling a sequence of non-trivial representations against each other.”
