Monodromy-Matrix Description of Extremal Multi-centered Black Holes
Jun-ichi Sakamoto, Shinya Tomizawa
We study solution-generating techniques based on the Breitenlohner--Maison linear system for extremal, stationary biaxisymmetric black hole solutions in five-dimensional s…
Multi-centered Myers-Perry Black Holes in Five Dimensions
Shinya Tomizawa, Jun-ichi Sakamoto, Ryotaku Suzuki
We present a new family of multi-centered rotating black hole solutions in 5D vacuum Einstein gravity, providing explicit examples of cohomogeneity-three spacetimes. It is well kno…
Monodromy-Matrix Description of Doubly Rotating Black Rings
Jun-ichi Sakamoto, Shinya Tomizawa
Extending the single-angular-momentum case analyzed in our previous work, we investigate the solution-generating technique based on the Breitenlohner-Maison (BM) linear system for…
Description of Non-Spherical Black Holes in 5D Einstein Gravity via the Riemann-Hilbert Problem
Jun-ichi Sakamoto, Shinya Tomizawa
We investigate the solution-generating technique based on the Breitenlohner-Maison (BM) linear system, for asymptotically flat, stationary, bi-axisymmetric black hole solutions wit…
Asymmetric dyonic multi-centered rotating black holes
Shinya Tomizawa, Jun-ichi Sakamoto, Ryotaku Suzuki
We construct an exact solution in four-dimensional Einstein-Maxwell-dilaton theory, describing multi-centered rotating black holes carrying both electric and magnetic charges, obta…
Building multi-BTZ black holes through Riemann-Hilbert problem
Jun-ichi Sakamoto, Shinya Tomizawa
We construct a recently found class of non-BPS black hole solutions with asymptotically in type IIB supergravity, consisting of multiple BTZ black holes…
