构造了二维bstractOff-shell(4,q)超多重态,其中q = 1,2,4.这些被用来构造目标空间是有挠超凯勒的sigma模型。离壳超对称性意味着这三个复杂结构是同时可积的,并允许我们使用扩展超空间和射影超空间来构造作用,给出目标空间几何的显式构造。
A bstractOff-shell (4, q) supermultiplets in 2-dimensions are constructed for q = 1, 2, 4. These are used to construct sigma models whose target spaces are hyperkähler with torsion. The off-shell supersymmetry implies the three complex structures are simultaneously integrable and allows us to construct actions using extended superspace and projective superspace, giving an explicit construction of the target space geometries.
