Stringy Tachyonic Instabilities of Non-Supersymmetric Ricci Flat Backgrounds
Bobby Samir Acharya, Gerardo Aldazabal, Eduardo Andrés +3
Superstring/M-theory compactified on compact Ricci flat manifolds have recently been conjectured to exhibit instabilities whenever the metrics do not have special holonomy. We use…
Particle models from orientifolds at Gepner-orbifold points
G. Aldazabal, E. C. Andrés, J. E. Juknevich
We consider configurations of stacks of orientifold planes and D-branes wrapped on a non trivial internal space of the structure {(Gepner model)^{c=3n} x T^{2(3-n)}}/Z_N, for n=1,2…
Type IIB orientifolds on Gepner points
Gerardo Aldazabal, Eduardo C. Andrés, Mauricio Leston +1
We study various aspects of orientifold projections of Type IIB closed string theory on Gepner points in different dimensions. The open string sector is introduced, in the usual co…
Nondiagonal Coset Models and their PoincarÉ Polynomials
G. Aldazabal, I. Allekotte, E. Andrés +1
coset models of the type with nondiagonal modular invariants for both and are considered. Poincaré polynomials of the correspondi…
