Query: Aspects of non-associative structures in physics   We summarize the emergence of non-commutative/non-associative structures in
Dirac's generalization of Maxwell theory, focusing mostly on the magnetic field
analogue of the non-geometric R-flux string model. The cohomological
interpretation of the obstructions to associativity in terms of 3-cocycles and
the use of the star product as alternative to ordinary quantization are also
discussed in this context.
