Detailed Description

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

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

Details

The implemented equation is:

\[ \eth F = \eth^\prime F - (1 - y) \frac{\eth R}{R} \partial_y F, \]

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