comment What is the role of B-field $B \in H^2(X,\mathbb{R}/\mathbb{Z})$ in mathematics?
@GunnarMagnusson Perhaps the OP is looking for connections to other parts of mathematics? The mirror symmetry B-field is a cohomological shadow of more complicated objects.

In what sort of mathematics? The $B$-field can have many roles, dpeend on context.

comment Have Dirac's negative probabilities been furthered in modern probability theory?
This question is based on a misunderstanding of what Dirac meant by negative probabilities. They were a bug in a model he was considering, not a new mathematical concept he wanted to introduce. This question should be closed.

comment Explanations for mathematicians, about the falsifiability (or not) of string theory
@SebastienPalcoux I think you may be confused about the purpose of MathOverflow. Please take the advice Will Jagy gave you on Meta.

@SebastienPalcoux: It's standard practice on MathOverflow to explain why you've downvoted a question. Aaron was correct to put the comment where he did.

comment are moduli stacks deligne-mumford stacks in general
The question specifies 'over the complex numbers', which rules out all of the examples listed so far. I think Ravi's right that we should expect DM in the case of complex algebraic objects with finite automorphism groups.

comment Geometric treatment of the Ward-Takahashi identity
@JeffHarvey All true. I've only sketched out the basic idea above. The OP didn't write enough for me to bother with more than that.
