Rigidity for Lorentzian metrics with the same length of null-geodesics
Gregory Eskin
We study the Lorentzian metric independent of the time variable in the cylinder where is the time variable and is a bounded smooth domain…
Determination of black holes by boundary measurements
Gregory Eskin
For a wave equation with time-independent Lorentzian metric consider an initial-boundary value problem in , where , is the time variable and…
Hawking type radiation from acoustic black holes with time-dependent metric
Gregory Eskin
We consider a time-dependent acoustic metric in 2+1 dimensions having a black hole and we study the Hawking type radiation from such black hole. We construct eikonals of special fo…
New examples of Hawking radiation from acoustic black holes
Gregory Eskin
Rotating acoustic metrics may have black holes inside the ergosphere. Simple cases of acoustic black holes were studied in the references [21], [4]. In the present paper we study t…
Hawking radiation from not-extremal and extremal Reissner-Nordstrom black holes
Gregory Eskin
We consider the non-extremal Reissner-Nordstrom black hole and construct a wave packet that exhibits the Hawking radiation. We find the average of the number of the created particl…
Behavior of null-geodesics in the interior of Reissner-Nordstrom black hole
Gregory Eskin
We show that an incoming null-geodesic belonging to a plane passing through the origin and starting outside the outer horizon crosses the outer and the inner horizons. Then it turn…
