B/2 model -- also exists -- classically, can be related <strong>to</strong> (0,2) A model by exchanging E and E ∨ -- but there’s a different regularization of the theory. For some special curves, in which φ ∗ E ∼ = φ ∗ E ∨ the A, B models are classically indistinguishable, but QM’ly are distinguished by their extensions over compactification divisor (ES, S Katz)
So far: * outlined A/2, B/2 models (first exs of `holomorphic field theories,’ rather than `<strong>to</strong>pological field theories’) * outlined quantum sheaf cohomology, old claims of ABS, verification Next: (2,2) & (0,2) Landau-Ginzburg models
