If anyone shows up, this is my most postponed talk

Various aspects of mathematical physics gave rise to what is called $H$-flux and later to

$f$-,  $Q$- and $R$-flux. 

 

On a  manifold, $H$-flux can be identified with a closed 3-form.

 

Given a bivector field $\rho$,   the $R$-flux `dual' to $H$ is a 3-vector field,

 related to an anomaly/failure  of  the Jacobi identity. 

 \p

  That anomaly hints at  curved and 

$L_\infty$-structures

which we investigate further.

 will include an explanation in mathematical terms of what physicists call \emph{flux}.

This is  work \emph{in progress} with

Andreas Deser and \\ Tom Lada.
