The Schwarzschild Solution in the 4-Dimensional Kaluza-Klein Description of The Einstein's Equations
J. H. Yoon, S. K. Oh, C. M. Kim +1
The Kaluza-Klein formalism of the Einstein's theory, based on the (2,2)-fibration of a generic 4-dimensional spacetime, describes general relativity as a Yang-Mills gauge theory on…

A Proposal of Positive-Definite Local Gravitational Energy Density in General Relativity
J. H. Yoon
We propose a 4-dimensional Kaluza-Klein approach to general relativity in the (2,2)-splitting of space-time using the double null gauge. The associated Lagrangian is equivalent to…

(1+1)-Dimensional Methods for General Relativity
J. H. Yoon
This is an article contributed to the Brill Festschrift, in honor of the 60th birthday of Prof. D.R. Brill, which will appear in the Vol.2 of the Proceedings of the International S…
