Constructing a Sequence with Given Limit Points

Click For Summary
SUMMARY

The discussion centers on constructing a sequence {a_n} with given limit points {y_j} such that {a_n} does not equal any {y_j} for all n and j. The Bolzano-Weierstrass theorem is referenced as a foundational concept. A proposed solution involves selecting points at a specified distance from each limit point {y_j}, gradually decreasing the distance for subsequent points. This method ensures that the sequence converges to the limit points while maintaining the required conditions.

PREREQUISITES
  • Understanding of the Bolzano-Weierstrass theorem
  • Familiarity with sequences and limit points in real analysis
  • Knowledge of convergence criteria for sequences
  • Basic skills in constructing mathematical proofs
NEXT STEPS
  • Study the Bolzano-Weierstrass theorem in detail
  • Explore examples of sequences with specified limit points
  • Learn about convergence and divergence of sequences
  • Investigate techniques for constructing sequences in real analysis
USEFUL FOR

Mathematics students, particularly those studying real analysis, educators teaching sequence convergence, and anyone interested in advanced mathematical concepts related to limit points.

Homework Statement


Let {y_j} be N given real numbers. Construct a sequence {a_n} so that {y_j} is the set of limit points of {a_n}, but a_n ≠ y_j for any n or j.

The Attempt at a Solution


Have no idea how to go about it.

I'd really appreciate any help on this

how about this, for the first n points, sequentially pick a point at a distance of from each of the yj,
for the next n, r/2 and so on.
