On the equivalence theorem in f(R)-type generalized gravity
Y. Ezawa, H. Iwasaki, Y. Ohkuwa +3
We investigate whether the equivalence theorem in f(R)-type gravity is valid also in quantum theory. It is shown that, if the canonical quantization is assumed, equivalence does no…
Gravitational waves originated before compactification in Kaluza-Klein theory
T. Ezawa, H. Iwasaki, A. Nakamura +2
We investigate the propagation of multidimensional gravitational waves generated before compactification and observes today as 4-dimensional gravitational waves and gauge fields by…
A canonical formalism of f(T)-type gravity in terms of Lie derivatives
Y. Ezawa, H. Iwasaki, Y. Ohkuwa +3
A canonical formalism of f(R)-type gravity is proposed, resolving the problem in the formalism of Buchbinder and Lyakhovich(BL). The new coordinates corresponding to the time deriv…
Correspondence between the first and the second order formalism in the generalized gravity of f(R)-type
Y. Ezawa, H. Iwasaki, Y. Ohkuwa +2
We clarify the correspondence between the first order formalism and the second order formalism in the generalized gravity where the Lagrangian density is given by a function of the…
