SUMMARY

The discussion centers on proving properties of an ordered ring, specifically that if R+ is well-ordered, then the minimum of R+ is 1 and that R is an integer ring. The participants emphasize the importance of establishing the existence of min(R+) and suggest assuming it is not 1 to derive a contradiction. This logical approach is essential for solving the problem effectively.

PREREQUISITES
  • Understanding of ordered rings and their properties
  • Familiarity with well-ordering principles
  • Knowledge of integer rings and their characteristics
  • Experience with proof techniques, particularly contradiction
NEXT STEPS
  • Study the properties of well-ordered sets in set theory
  • Learn about the structure and properties of integer rings
  • Explore proof techniques involving contradiction in mathematical logic
  • Investigate the implications of minimum elements in ordered sets
USEFUL FOR

Mathematicians, students studying abstract algebra, and anyone interested in the properties of ordered rings and their applications in mathematical proofs.

Let R be an ordered Ring. Assume R+ is well-ordered
Prove:
a) min(R+) = 1.
b) R is an integer ring

Sounds like a homework problem all right.

You didn't say it, but I assume you're looking for help? What have you done (successful or not), and where are you stuck?
 
(1) Why does min(R+) exist?
(2) Let u = min(R+), assume it is not 1, try to get a contradiction.
