Boundary states, matrix factorisations and correlation functions for the E-models
Christoph A. Keller, Sebastiano Rossi
The open string spectra of the B-type D-branes of the N=2 E-models are calculated. Using these results we match the boundary states to the matrix factorisations of the correspondin…
Bulk induced boundary perturbations
Stefan Fredenhagen, Matthias R. Gaberdiel, Christoph A. Keller
The influence of closed string moduli on the D-brane moduli space is studied from a worldsheet point of view. Whenever a D-brane cannot be adjusted to an infinitesimal change of th…
Matrix factorisations and D-branes on K3
Ilka Brunner, Matthias R. Gaberdiel, Christoph A. Keller
D-branes on K3 are analysed from three different points of view. For deformations of hypersurfaces in weighted projected space we use geometrical methods as well as matrix factoris…
