利用超对称性导出了IIB型超引力有效作用的高导数项的条件。利用这些条件，我们能够证明先前的猜想，即相对于Einstein-Hilbert项的阶$({\ensuremath{\alpha}}^{\ensuremath{'}}{)}^{3}$的模不变相互作用与SL（2，Z）基域上拉普拉斯算子的本征函数成正比。我们还讨论了这些参数如何推广到${\ensuremath{\alpha}}^{\ensuremath{'}}中的高阶项以及超引力的紧化。
Supersymmetry is used to derive conditions on higher derivative terms in the effective action of type IIB supergravity. Using these conditions, we are able to prove earlier conjectures that certain modular invariant interactions of order $({\ensuremath{\alpha}}^{\ensuremath{'}}{)}^{3}$ relative to the Einstein-Hilbert term are proportional to eigenfunctions of the Laplace operator on the fundamental domain of SL(2,Z). We also discuss how these arguments generalize to terms of higher order in ${\ensuremath{\alpha}}^{\ensuremath{'}},$ as well as to compactifications of supergravity.
