Abstract
Witt rings for nondegenerate forms of degree over a field of characteristic 0 or greater than were defined by Harrison and Pareigis. We revisit and discuss their definition as well as some special cases, classify the -forms employed in their definition, and define Witt rings of diagonal forms of degree . We also define two new Witt rings for nondegenerate forms of degree .
