论文摘要
我们构建了一个未折叠的系统，用于在4D反DE保姆空间中进行任意整数自旋的外壳磁场。为此，我们将编码fronsdal方程的壳系统与外部fronsdal电流相结合，为此我们找到了一个展开的公式。我们提出了Fronsdal电流系统的减少，该系统将其带入了展开的Fierz-Pauli系统，描述了任意整数旋转的大量领域。重新定义非螺旋高旋转系统作为schwinger-dyson方程组的集合，我们直接从展开的方程式计算了de donder仪表中的高旋转电场的繁殖物。我们发现了可大大简化此计算的操作员，从而可以直接从展开的系统中提取波动方程。
We construct an unfolded system for off-shell fields of arbitrary integer spin in 4d anti-de Sitter space. To this end we couple an on-shell system, encoding Fronsdal equations, to external Fronsdal currents for which we find an unfolded formulation. We present a reduction of the Fronsdal current system which brings it to the unfolded Fierz-Pauli system describing massive fields of arbitrary integer spin. Reformulating off-shell higher-spin system as the set of Schwinger-Dyson equations we compute propagators of higher-spin fields in the de Donder gauge directly from the unfolded equations. We discover operators that significantly simplify this computation, allowing a straightforward extraction of wave equations from an unfolded system.
