Pseudotensor

A Tensor-like object which reverses sign under inversion. Given a transformation Matrix ${\hbox{\sf A}}$,

\begin{displaymath}
{A_{ij}}' = \mathop{\rm det}\vert\,{\hbox{\sf A}}\vert a_{ik}a_{jl}A_{kl},
\end{displaymath}

where det is the Determinant. A pseudotensor is sometimes also called a Tensor Density.
