在之前的一篇论文中，我们提出了一种将两个电荷黑洞的熵与四维N=4超对称异质弦理论中的基本弦态简并联系起来的具体途径。对于环面紧化，如果考虑到全纯异常对黑洞熵公式的修正，则该建议适用于逆电荷的幂级数展开中的所有阶。在本文中，我们证明了类似的一致性也适用于其他N=4超对称异质弦紧化。
In a previous paper we had proposed a specific route to relating the entropy of two charge black holes to the degeneracy of elementary string states in N=4 supersymmetric heterotic string theory in four dimensions. For toroidal compactification this proposal works correctly to all orders in a power series expansion in inverse charges provided we take into account the corrections to the black hole entropy formula due to holomorphic anomaly. In this paper we demonstrate that similar agreement holds also for other N=4 supersymmetric heterotic string compactifications.
