标题： All minimal supergravity extensions of 2d dilaton theories

摘要： 二维稀释子理论的表述，如球对称约化的爱因斯坦引力，通过作为具有非零玻色扭曲的首阶理论的表述方式得到了极大的简化。 这一点在量子层面上尤其成立。 发现将超扩展解释为分级泊松sigma模型可以普遍覆盖所有可能的二维超引力。 完全避免了超场和因此产生的多余辅助场。 该过程表明，玻色二维模型的推广高度模糊。 显示英文摘要

摘要： The formulation of 2d-dilaton theories, like spherically reduced Einstein gravity, is greatly facilitated in a formulation as a first order theory with nonvanishing bosonic torsion. This is especially also true at the quantum level. The interpretation of superextensions as graded Poisson sigma models is found to cover generically all possible 2d supergravities. Superfields and thus superfluous auxiliary fields are avoided altogether. The procedure shows that generalizations of bosonic 2d models are highly ambiguous.
