SUMMARY

The discussion centers on the properties of alternating tensors, specifically the relationship defined by the mapping Alt. It is established that if \(\omega\) is an alternating tensor, then Alt(\(\omega\)) equals \(\omega\). Furthermore, the converse is confirmed: if Alt(\(\omega\)) equals \(\omega\), then \(\omega\) must indeed be an alternating tensor. This establishes a definitive equivalence between the tensor and its alternating form.

If [itex]\omega[/itex] is an alternating tensor, then [itex]Alt(\omega)=\omega[/itex], where Alt is the mapping that maps any tensor to an alternating tensor.

I guess the converse is also true, i.e., if [itex]Alt(\omega)=\omega[/itex], then [itex]\omega[/itex] must be an alternating tensor. Am I right?

If you have w=Alt(w), and Alt(w) is an alternating tensor...
