Making given metric space bounded

Click For Summary
SUMMARY

The discussion centers on the claim that for any metric space (X,d), there exists a topologically equivalent metric d' such that (X,d') is bounded. The proposed transformations for d' include d' = d/(1+d) and d' = min{1,d}. The user confirmed the validity of the min{1,d} transformation, indicating its effectiveness in creating a bounded metric space.

PREREQUISITES
  • Understanding of metric spaces and their properties
  • Familiarity with topological equivalence
  • Knowledge of metric transformations

I just encountered a claim, that for any given metric space (X,d), there exists another topologically equivalent metric d' so that (X,d') is bounded. Anyone knowing anything about the proof for this?

Try putting d'=d/(1+d) or min{1,d}.
 
Ok. I checked the min{1,d} one.
