我们推导了最小超对称六维引力理论及其f -理论实现中阿贝尔规范群因子数目的界。正如最近在文献中提出的那样，这些界限要求理论谱中某些BPS弦的一致性。在某些假设下，这种方法限制了六维超引力理论中至少有一个张量倍乘的阿贝尔规范群因子的数量为$N leq 20$（或在没有带电物质的情况下为$N leq 22$）。对于任何具有至少一个张量多重的几何f理论实现，我们通过要求即使在没有微扰杂散对偶的情况下也存在的杂散孤子弦的统一性，建立了界$N leq 16$。这一结果推广到四维f理论真空上的任何理性振动的爆破。我们的发现导致了椭圆纤维Calabi-Yau三倍体的modell - weil群秩的普遍界限。
We derive bounds on the number of abelian gauge group factors in six-dimensional gravitational theories with minimal supersymmetry and in their F-theoretic realisations. These bounds follow by requiring consistency of certain BPS strings in the spectrum of the theory, as recently proposed in the literature. Under certain assumptions this approach constrains the number of abelian gauge group factors in six-dimensional supergravity theories with at least one tensor multiplet to be $N leq 20$ (or $N leq 22$ in absence of charged matter). For any geometric F-theory realisation with at least one tensor multiplet we establish the bound $N leq 16$ by demanding unitarity of a heterotic solitonic string which exists even in absence of a perturbative heterotic dual. This result extends to four-dimensional F-theory vacua on any blowup of a rational fibration. Our findings lead to universal bounds on the rank of the Mordell-Weil group of elliptically fibered Calabi-Yau threefolds.
