From boundaries to conditions over superspace
نویسنده
چکیده
N = 1 and 2 superconformal boundary conditions are shown to be the consequence of a “boundary” on the worldsheet superspace with positive codimension in the anticommuting subspace. In addition to the well-known boundary conditions, I also find two new infinite series of N = 2 boundary states. Their free field realizations are given. A self-contained development of 2d superspace leads to new perspectives on this subject.

Rigid supersymmetry with boundaries
We construct rigidly supersymmetric bulk-plus-boundary actions, both in x-space and in superspace. For each standard supersymmetric bulk action a minimal supersymmetric bulk-plus-boundary action follows from an extended F or D-term formula. Additional separately supersymmetric boundary actions can be systematically constructed using co-dimension one multiplets (boundary superfields). We also di...
متن کاملA Survey on Precision of Nested Water Level Data Derived From Delft3D Model
One of the troublesome aspects of numerical modeling is to determine open boundaries for a model and to make sure that the boundary conditions employed at the open boundaries are compatible with physical processes being simulated within the interior of the model domain. In this investigation the accuracy of the water level data derived from delft3D employing nesting procedure were studied. Thes...
متن کاملEffect of Fuzzy Boundaries on the Bearing Capacity of Footings on Two-Layered Clay
In this study, fuzzy logic was implemented to formulate the fuzziness of layer boundaries for a two-layered clay soil. A field of two-layered clay with fuzzy boundaries between layers was generated, and then the bearing capacity of strip footing on this field was calculated by the assumption of plane-strain conditions. The Mohr-Coulomb failure criterion was used and bearing capacity calculation...
متن کاملsuperspace for the type IIA superstring and D-branes
We lift the bosonic AdS4 × CP 3 solution of type IIA supergravity preserving 24 supersymmetries to a D = 10 superspace which has 32 Grassmann–odd directions. The type IIA superspace is obtained from D = 11 via dimensional reduction of the coset superspace OSp(8|4)/SO(7) × SO(1, 3) by realizing the latter as a Hopf fibration over the former. This construction generalizes to superspace the Hopf f...
متن کاملSuperspace extrapolation reveals inductive biases in function learning
We introduce a new approach for exploring how humans learn and represent functional relationships based on limited observations. We focus on a problem called superspace extrapolation, where learners observe training examples drawn from an n-dimensional space and must extrapolate to an n+ 1dimensional superspace of the training examples. Many existing psychological models predict that superspace...
