Covariantly constant forms on torsionful geometries from world-sheet and spacetime perspectives
P. S. Howe, George Papadopoulos, Vid Stojevic
The symmetries of two-dimensional supersymmetric sigma models on target spaces with covariantly constant forms associated to special holonomy groups are analysed. It is shown that…
Two-Dimensional Supersymmetric Sigma Models on Almost-Product Manifolds and Non-Geometry
Vid Stojevic
We show that the superconformal symmetries of the (1,1) sigma model decompose into a set of more refined symmetries when the target space admits projectors , and the ortho…
Doubled Formalism, Complexification and Topological Sigma-Models
Vid Stojevic
We study a generalization of the Alexandrov-Kontsevich-Schwarz-Zaboronsky (AKSZ) formulation of the A- and B-models which involves a doubling of coordinates, and can be understood…
Topological A-Type Models with Flux
Vid Stojevic
We study deformations of the A-model in the presence of fluxes, by which we mean rank-three tensors with antisymmetrized upper/lower indices, using the AKSZ construction. Generical…
Special Holonomy and Two-Dimensional Supersymmetric Sigma-Models
Vid Stojevic
Two-dimensional sigma-models describing superstrings propagating on manifolds of special holonomy are characterized by symmetries related to covariantly constant forms that these m…
On the symmetries of special holonomy sigma models
P. S. Howe, V. Stojevic
In addition to superconformal symmetry, (1,1) supersymmetric two-dimensional sigma models on special holonomy manifolds have extra symmetries that are in one-to-one correspondence…
