In school I've always learned that tensor transformations took the form of:(adsbygoogle = window.adsbygoogle || []).push({});

[tex]\mathbf{Q'}=\mathbf{M} \times \mathbf{Q} \times \mathbf{M}^T [/tex]

However, in all the recent papers I've been reading. They've been doing the transformation as:

[tex]\mathbf{Q'}= \frac {\mathbf{M} \times \mathbf{Q} \times \mathbf{M}^T}{det(\mathbf{M})}[/tex]

Where Q is the tensor in question and M is the transformation matrix and M^T is the transpose of M.

Does anyone know why the difference?
