Intersection Between SFT and Condensed Matter
... The star algebra is formed by vertex operators and the operator K. The simplest subalgebra relevant for tachyon condensation is therefore spanned by K and c. Let us be more generous and add an operator B such that QB=K. ...

The Atiyah-Singer index theorem: what it is and why
... In certain cases (when M is a spin manifold: w2 = 0), there is a distinguished Dirac operator D acting between sections of the spinor bundle S over M . One can then ‘twist’ this basic Dirac operator D : L2 (M ; S) −→ L2 (M ; S) by tensoring with an arbitrary vector bundle E, to get the twisted Dira ...
