Symmetry-breaking boundary states for WZW models
Daniel Blakeley, Andreas Recknagel
Starting with the SU(2)_k WZW model, we construct boundary states that generically preserve only a parafermion times Virasoro subalgebra of the full affine Lie algebra symmetry of…

Non-commutative Weitzenboeck geometry, gerbe modules, and WZW branes
Andreas Recknagel, Rafal R. Suszek
We study the non-commutative matrix model which arises as the low-energy effective action of open strings in WZW models. We re-derive this fuzzy effective gauge dynamics in two dif…

J. Froehlich, O. Grandjean, A. Recknagel
This is an expanded version of the notes to a course taught by the first author at the 1995 Les Houches Summer School. Constraints on a tentative reconciliation of quantum theory a…
