Rings and Fields- how to prove Z[x]/pZ[x] is an integral domain

Click For Summary
SUMMARY

The discussion focuses on proving that the quotient ring Z[x]/pZ[x], where p is a prime natural number, is an integral domain. Participants note that this quotient ring is isomorphic to (Z/p)[x], which is established as an integral domain. The key challenge lies in demonstrating the isomorphism between these two structures and confirming the integral domain property through appropriate mappings.

PREREQUISITES
  • Understanding of quotient rings in abstract algebra
  • Familiarity with prime numbers and their properties
  • Knowledge of isomorphisms in ring theory
  • Basic concepts of integral domains
NEXT STEPS

Homework Statement



Prove Z[x]/pZ[x] is an integral domain where p is a prime natural number.

Homework Equations



I've seen in notes that this quotient ring can be isomorphic to (z/p)[x] and this is an integral domain but I don't know how to prove there is an isomorphism between them and how to prove it is an integral domain...

Do you have any suggestion about what the isomorphism will be?? Just write down some map that looks intuitively right, most of the time this works.
