Detailed Description

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

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

Details

The implemented equation is:

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

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