Detailed Description

template<typename ArgumentTag>
struct Cce::ApplySwshJacobianInplace< Spectral::Swsh::Tags::Derivative< ArgumentTag, Spectral::Swsh::Tags::EthbarEth > >

Specialization for the spin-weighted derivative \(\bar{\eth} \eth\).

Details

The implemented equation is:

\[ \bar{\eth} \eth F = \bar{\eth}^\prime \eth^\prime F - \frac{\eth R \bar{\eth} R}{R^2} (1 - y)^2 \partial_y^2 F - (1 - y)\left(\frac{\eth R}{R} \bar{\eth} \partial_y F + \frac{\bar{\eth} R}{R} \eth \partial_y F + \frac{\eth \bar\eth R}{R} \partial_y F\right), \]

where \(\bar{\eth} \eth\) is the derivative at constant Bondi radius \(r\) and \(\bar{\eth}^\prime \eth^\prime\) is the derivative at constant numerical radius \(y\).
