摘要

我们提出了M理论中具有一般磁荷的AdS4 BPS黑洞的熵函数，特别解决了长期存在的关于重子电荷的难题。熵函数是由一个仅以内部流形的拓扑数据定义的重力块构造的。我们证明扭曲黑洞的熵总是可以被重新表述为一个i极化问题——即使在现有的大n场理论计算无法提供答案的情况下。此外，我们正确地再现了一类具有纯重子磁荷的已知黑洞的熵。我们的结果提供了M理论中AdS4黑洞的一般引力块的猜想，并预测了一些鞍点尚未找到的配分函数的大n极限。2025年由美国物理学会出版

I -Extremization with Baryonic Charges

We propose an entropy function for AdS4 BPS black holes in M theory with general magnetic charges, resolving in particular a long-standing puzzle about baryonic charges. The entropy function is constructed from a gravitational block defined solely in terms of topological data of the internal manifold. We show that the entropy of twisted black holes can always be reformulated as an I-extremization problem—even in cases where existing large-N field theory computations fail to provide an answer. Furthermore, we correctly reproduce the entropy for a class of known black holes with purely baryonic magnetic charges. Our results offer both a conjecture for the general gravitational block for AdS4 black holes in M theory and a prediction for the large-N limit of several partition functions whose saddle points have yet to be found.
