Nonlinear completion of massive gravity of the Fierz-Pauli type
Shinji Hamamoto
A possible nonlinear completion of massive gravity of the Fierz-Pauli type is proposed. The theory describes a system consisting of a massive tensor field of the Fierz-Pauli type a…

Possible Nonlinear Completion of Massive Gravity
Shinji Hamamoto
Possible nonlinear completion of massive gravity is presented. An additional scalar ghost contained in linear theory condensates to give rise to positive-energy excitations.

Higher Derivatives and Canonical Formalism
Shinji HAMAMOTO
A canonical formalism for higher-derivative theories is presented on the basis of Dirac's method for constrained systems. It is shown that this formalism shares a path integral exp…
