We derive monogamy relations (tradeoffs) between strengths of violations of Bell's inequalities from the nonsignaling condition. Our result applies to general Bell inequalities with an arbitrary large number of partners, outcomes, and measurement settings. The method is simple, efficient, and does not require linear programing. The results are used to derive optimal fidelity for asymmetric cloning in nonsignaling theories.
我们从无信号条件推导出贝尔不等式违背强度之间的一夫一妻制关系（权衡）。我们的结果适用于具有任意大量参与者、结果和测量设置的一般贝尔不等式。该方法简单、高效，且不需要线性规划。这些结果被用于推导无信号理论中不对称克隆的最优保真度。
