Detailed Description

template<typename DataType>
struct Ccz4::Tags::TraceATilde< DataType >

The trace of the trace-free part of the extrinsic curvature.

Details

We define:

\begin{align} tr\tilde{A} &= \tilde{\gamma}^{ij} \tilde{A}_{ij} \end{align}

where \(\tilde{\gamma}^{ij}\) is the inverse conformal spatial metric defined by Ccz4::Tags::InverseConformalMetric and \(\tilde{A}_{ij}\) is the trace-free part of the extrinsic curvature defined by Ccz4::Tags::ATilde.
