Idea

In (2d) conformal field theories, certain fermion-fields may be re-expressed as chiral boson fields – this is called bosonization.

The converse of bosonization explains for instance why chiral bosons have partition functions like Pfaffian line bundles in 2d, namely theta functions (…) (Alvares-Gaumé-, Bost, Moore, Nelson & Vafa 1987).
