Consistent Hamiltonian Reduction
Jong Hyuk Yoon
I show that the recently proposed (2+2) Hamiltonian reduction of Einstein's equations of 4-dimensional spacetimes is consistent with general covariance. The consistency proof is {\…
Poisson algebra of quasilocal angular momentum and its asymptotic limit
Jong Hyuk Yoon, Seung Hun Oh
We study the previously proposed quasilocal angular momentum of gravitational fields in the absence of isometries. The quasilocal angular momentum has the following attracti…
Solution-generating methods of Einstein's equations by Hamiltonian reduction
Seung Hun Oh, Kyoungtae Kimm, Yongmin Cho +1
The purpose of this paper is to demonstrate a new method of generating exact solutions to the Einstein's equations obtained by the Hamiltonian reduction. The key element to the suc…
Problem of time and Hamiltonian reduction in the (2+2) formalism
Jong Hyuk Yoon
We apply the Hamiltonian reduction procedure to general spacetimes of 4-dimensions in the (2+2) formalism and find privileged spacetime coordinates in which the physical Hamiltonia…
Dynamical surface gravity
Alex B. Nielsen, Jong Hyuk Yoon
We discuss how the surface gravity can be classically defined for dynamical black holes. In particular we focus on defining the surface gravity for locally defined horizons and com…
(1+1)-dimensional formalism and quasi-local conservation equations
Jong Hyuk Yoon
A set of exact quasi-local conservation equations is obtained in the (1+1)-dimensional description of the Einstein's equations of (3+1)-dimensional spacetimes. These equations are…
