added pointer to:
I have given the references on the higher geometric formulation its own subsection (here) and then I have added these:
The automorphism 2-group of the T-duality 2-group (and hence potentially the full structure of T-folds) is determined in:
Introduction and review:
Proposals for further generalization (2-connections and further non-geometric backgrounds):
slightly expanded and re-organized the Idea-text. (But it remains a stub.)
]]>Finally Thomas Nikolaus and Konrad Waldorf have written up their formalization of Chris Hull’s idea of T-folds, in terms of the higher differential geometry of principal 2-bundles for the T-duality 2-group. I have added a pointer as Nikolaus-Waldorf 18.
]]>so for completeness I gave T-duality 2-group its own entry
]]>added a pointer to Thomas Nikolaus’ talk as of yesterday to T-fold.
(I wish there were more to link to at the moment, but at least the broad statement should be recorded for the time being.)
