Black hole topology
WebJan 26, 2024 · But in topology, shapes are flexible things, as if made from rubber. A topologist is free to stretch and twist a shape. Even cutting and gluing are allowed, as … WebWe study the thermodynamic topology of four dimensional dyonic Anti-de-Sitter(AdS) black hole in three different ensembles: canonical, mixed and grand canonical ensemble. While canonical ensemble refers to the ensemble with fixed electric and magnetic charges, mixed ensemble is an ensemble where we fix magnetic charge and electric potential. In the …

Did you know?
In networking, a black hole refers to a place in the network where incoming or outgoing traffic is silently discarded (or "dropped"), without informing the source that the data did not reach its intended recipient. When examining the topology of the network, the black holes themselves are invisible, and can only be detected by monitoring the lost traffic; hence the name as astronomical Black holes cann… WebAjeet’s current research with Dr. Noble at NASA GSFC uses a ray tracing code around a Binary Black Hole (BBH) spacetime to measure and …
WebJun 9, 2006 · Hawking’s theorem on the topology of black holes asserts that cross sections of the event horizon in 4-dimensional asymptotically flat stationary black hole spacetimes obeying the dominant energy condition are topologically 2-spheres. This conclusion extends to outer apparent horizons in spacetimes that are not necessarily … WebNov 24, 2011 · [3][4][5] [6] A topology on a higher-dimensional black hole is reviewed in Ref. 7, which shows how the topology of a cross section of a black hole in five-dimensional stationary vacuum space-time ...
