AI 中文摘要
我们在加倍的 IIB 型理论中构造了一个四维双荷黑洞电荷轨道的渐近平坦 T 折代表。从 F1 - P - NS5 - KKM 环面种子出发，对一个活跃的加倍三维环面施加积分抛物 T 对偶单值性。非几何数据仅通过这种全局拼接进入：雷斯纳 - 诺德斯特龙型项由加倍的卡鲁扎 - 克莱因/缠绕局部系统中的守恒四维电场和磁场强度产生，而非仅由内部代数 Q 通量产生。精确对偶性保留了局部方程、BPS 指标以及控制熵的 NS - NS / \(N = 4\)电荷子格的\(O(6,6)\)不变量。最小爱因斯坦 - 麦克斯韦 - 伸缩子切片包含一个跑动标量分支和等电荷雷斯纳 - 诺德斯特龙极限；极端近视界区域局部为\(\mathrm{AdS}_2\times S^2\)，紧致因子通过全局 T 对偶拼接。
英文摘要
We construct an asymptotically flat T-fold representative of a four-dimensional dyonic black-hole charge orbit in doubled type-IIB theory. Starting from the F1-P-NS5-KKM toroidal seed, an integral parabolic T-duality monodromy is imposed on an active doubled three-torus. The non-geometric data enter only through this global patching: the Reissner-Nordström-type term is sourced by conserved four-dimensional electric and magnetic field strengths in the doubled Kaluza-Klein/winding local system, not by an internal algebraic \(Q\)-flux alone. Exact duality preserves the local equations, the BPS index, and the \(O(6,6)\)-invariant of the NS-NS/\(N=4\) charge sublattice governing the entropy. The minimal Einstein-Maxwell-dilaton slice contains a running-scalar branch and an equal-charge Reissner-Nordström limit; the extremal near-horizon region is locally \(\mathrm{AdS}_2\times S^2\), with the compact factor globally T-duality patched.
