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.

comment What do correlation functions compute in CFT?
Are you asking for the physical meaning of the complex coordinates (the question Igor answered) or are you asking about the physical meaning of the states created by the $J(x)$ operators?
