Detailed Description

template<typename DataType, size_t Dim, typename Frame>
struct Ccz4::Tags::GammaHatMinusContractedConformalChristoffel< DataType, Dim, Frame >

The CCZ4 temporary expression ${\hat{Γ}}^{i} - {\tilde{Γ}}^{i}$ .

We define:

$\begin{aligned} (1) & {\hat{Γ}}^{i} - {\tilde{Γ}}^{i} & = 2 {\tilde{γ}}^{i j} Z_{j} \end{aligned}$

where ${\hat{Γ}}^{i}$ is the CCZ4 evolved variable defined by Ccz4::Tags::GammaHat, ${\tilde{Γ}}^{i}$ is the contraction of the conformal spatial Christoffel symbols of the second kind defined by Ccz4::Tags::ContractedConformalChristoffelSecondKind, ${\tilde{γ}}^{i j}$ is the inverse conformal spatial metric defined by Ccz4::Tags::InverseConformalMetric, and $Z_{i}$ is the spatial part of the Z4 constraint defined by Ccz4::Tags::SpatialZ4Constraint.
