The large level limit of Kazama-Suzuki models
Stefan Fredenhagen, Cosimo Restuccia
Limits of families of conformal field theories are of interest in the context of AdS/CFT dualities. We explore here the large level limit of the two-dimensional N=(2,2) superconfor…
Limit theories and continuous orbifolds
Cosimo Restuccia
Relativistic QFTs are in general defined by a collection of effective actions, describing the dynamics of quantum fields at different energy scales. The consequent natural idea of…
The geometry of the limit of N=2 minimal models
Stefan Fredenhagen, Cosimo Restuccia
We consider the limit of two-dimensional N=(2,2) superconformal minimal models when the central charge approaches c=3. Starting from a geometric description as non-linear sigma mod…
The limit of N=(2,2) superconformal minimal models
Stefan Fredenhagen, Cosimo Restuccia, Rui Sun
The limit of families of two-dimensional conformal field theories has recently attracted attention in the context of AdS/CFT dualities. In our work we analyse the limit of N=(2,2)…
DBI analysis of generalised permutation branes
Stefan Fredenhagen, Cosimo Restuccia
We investigate D-branes on the product GxG of two group manifolds described as Wess-Zumino-Novikov-Witten models. When the levels of the two groups coincide, it is well known that…
