Function Documentation

inline TensorSymmetries sequant::density::symmetries(std::wstring_view label, std::size_t rank)

Note

a multi-body spin-orbital density may also be perm-nonsymmetric: that is a spin component of it, as spin tracing produces

Returns:

the defining symmetries of the density tensor label of rank rank: a multi-body spin-orbital density (γ, η, κ) is antisymmetric, a spin-free one (Γ) and a 1-body one are not
