From Exact Stationary Kerr--Newman Inner-Horizon Geometry to a Compact APS Collar
Abstract
This preprint establishes a geometric-to-analytic bridge from the exact stationary subextremal Kerr--Newman inner-horizon geometry to a compact Atiyah--Patodi--Singer collar model for a specified intrinsic elliptic reduction. The paper works in the nondegenerate Kerr--Newman parameter regime\[0
