标题： Generalized Born--Infeld Actions and Projective Cubic Curves

摘要： 我们研究具有第二个非线性实现超对称性的$U(1)^{\,n}$超对称 Born-Infeld 拉格朗日量。 结果的非线性结构比标准 Born-Infeld 作用量中的平方根更为复杂，但包含三个矢量多重态的所有情况中确定这些模型的二次约束可以被精确求解。 相应的模型由三次全纯势函数分类。 它们的对称结构与射影三次流形相关。 显示英文摘要

摘要： We investigate $U(1)^{\,n}$ supersymmetric Born-Infeld Lagrangians with a second non-linearly realized supersymmetry. The resulting non-linear structure is more complex than the square root present in the standard Born-Infeld action, and nonetheless the quadratic constraints determining these models can be solved exactly in all cases containing three vector multiplets. The corresponding models are classified by cubic holomorphic prepotentials. Their symmetry structures are associated to projective cubic varieties.
