Variational principle of relativistic perfect fluid
Takayoshi Ootsuka, Muneyuki Ishida, Erico Tanaka +1
We reformulate the relativistic perfect fluid system on curved space-time. Using standard variables, the velocity field ,energy density and pressure , the covariant Euler…
Energy-momentum conservation laws in Finsler/Kawaguchi Lagrangian formulation
Takayoshi Ootsuka, Ryoko Yahagi, Muneyuki Ishida +1
We reformulate the standard Lagrangian formalism to a reparameterisation invariant Lagrangian formalism by means of Finsler and Kawaguchi geometry. In our formalism, various types…
Chiral gravity in higher dimensions
Takayoshi Ootsuka, Erico Tanaka, Kousuke Ura
We construct a chiral theory of gravity in 7 and 8 dimensions, which are equivalent to Einstein-Cartan theory using less variables. In these dimensions, we can construct such highe…
