SUMMARY

This discussion focuses on proving the non-existence of an embedding between the groups Z3 and Z. The user attempts to demonstrate that no embedding can exist due to the properties of the group Z3, specifically highlighting that in Z3, the equation 1 + 1 + 1 = 0 holds true. This characteristic indicates that Z3 is a finite group, while Z is infinite, thus confirming that an embedding cannot exist between these two groups.

PREREQUISITES
  • Understanding of group theory concepts, particularly embeddings.
  • Familiarity with finite and infinite groups.
  • Knowledge of modular arithmetic, specifically in the context of Z3.
  • Basic proficiency in mathematical proofs and logic.
NEXT STEPS
  • Study the properties of finite groups versus infinite groups in group theory.
  • Learn about group embeddings and their implications in algebra.
  • Explore modular arithmetic and its applications in group theory.
  • Investigate examples of embeddings between different groups to solidify understanding.
USEFUL FOR

Mathematics students, particularly those studying abstract algebra, group theorists, and educators seeking to deepen their understanding of group embeddings and properties of finite versus infinite groups.

Homework Statement


Show that there exists and embedding or show that an embedding can't exist between Z3 and Z.

The Attempt at a Solution


I've tried to find an embedding and can't so I've decided that an embedding can't exist but how does one show this?

Any suggestions would be great.
