SUMMARY

A field of order p² exists for every prime p, as established through the construction of monic quadratics in Zp[x]. The Frobenius endomorphism plays a crucial role in this proof, confirming the existence of such fields. The discussion highlights the importance of understanding polynomial rings and their properties in finite fields.

PREREQUISITES
  • Understanding of finite fields and their properties
  • Familiarity with polynomial rings, specifically Zp[x]

Homework Statement



Show that a field of order p2 exists for every prime p.


The Attempt at a Solution



In an earlier problem I found that there were p2 monic quadratics in Zp[x], but I don't know if that's useful. Any ideas or theorems would be super helpful, thanks!
