Could someone explain in a simple but accurate manner what extensors are as mathematical entities and how they are used?

How do extensors essentially differ from tensors?

Are there or could there be applications of extensors in physics?

Some related papers about the topic of extensors:

  • $\begingroup$ This appears to be a rather broad request, especially the "applications in physics" part, which is generally looked down upon as it's really asking for a list instead of an explanation. $\endgroup$ – Kyle Kanos Nov 15 '18 at 11:00
