Detailed Description

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

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

Details

We define:

$$\begin{array}{}\text{(1)}& tr\tilde{A}& ={\tilde{\gamma }}^{ij}{\tilde{A}}_{ij}\end{array}$$

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.
