Statistical anisotropy of primordial gravitational waves from generalized formalism
Takahiro Tanaka, Yuko Urakawa
In this letter, we demonstrate how to use the generalized formalism, which enables us to compute the evolution of all the large scale fluctuations, including gravitational wa…

g formalism
Takahiro Tanaka, Yuko Urakawa
The formalism has been the major computational tool to study the superhorizon evolution of the scalar type perturbation sourced by scalar fields. Recently, this formalism was…
