Title:
Supersymmetric Boundary Conditions in 3D N=2 Theories
Speaker:
Abstract:
We study supersymmetric boundary conditions in 3-dimensional N = 2 Landau-Ginzburg models and abelian gauge theories. In the Landau-Ginzburg model the boundary conditions that preserve (1,1) supersymmetry (A-type) and (2,0) supersymmetry (B-type) on the boundary are classified in terms of subspaces of the target space ("brane"). An A-type brane is a Lagrangian submanifold on which the imaginary part of the superpotential is constant, while a B-type brane is a holomorphic submanifold on which the superpotential is constant. We also discuss the abelian duality of N = 2 Maxwell theory and mirror symmetry of N = 2 SQED from the point of view of the boundary conditions.Related Papers:
