Fundamental Group of Quotient Space

Click For Summary
SUMMARY

The discussion centers on the relationship between the fundamental group of a quotient space and discrete subgroups within simply connected topological groups. Specifically, it establishes that if G is a simply connected topological group and H is a discrete subgroup, then the fundamental group \(\pi_1(G/H, 1)\) is isomorphic to H. Additionally, the conversation touches on finding the fundamental group of the circle \(S^1\) using covering spaces, suggesting a need for adjustments in the proof to accommodate this specific case.

PREREQUISITES
  • Understanding of fundamental groups in algebraic topology
  • Familiarity with covering spaces and their properties
  • Knowledge of simply connected topological groups
  • Concept of discrete subgroups in topology
NEXT STEPS

Hi

I don't know how to attack the following question, any hints would be appreciated:

If G is a simply connected topological group and H is a discrete subgroup, then \pi_1(G/H, 1) \cong H.Thank you

Do you know how to find the fundamental group of S^1 (using covering spaces). Can you adjust the proof a little bit such that it holds in this case??
