SUMMARY

The Cantor set is defined as the set of numbers in the interval [0, 1] that can be expressed in base 3 without using the digit 1. The number 1/4, when converted to ternary, is represented as 0.020202..., which does not contain the digit 1. Therefore, 1/4 is indeed a member of the Cantor set. This conclusion aligns with the established characteristics of the Cantor set regarding ternary expansions.

PREREQUISITES
  • Understanding of Cantor set properties
  • Knowledge of ternary numeral system
  • Familiarity with base conversions
  • Basic concepts of set theory
NEXT STEPS
  • Study the properties of the Cantor set in detail
  • Learn about ternary numeral system and its applications
  • Explore proofs related to set membership in Cantor sets
  • Investigate the implications of Cantor set characteristics in real analysis
USEFUL FOR

Mathematicians, students studying real analysis, and anyone interested in set theory and its applications in topology.

Can anyone show me a proof of 1/4 being in the cantor set?? My prof said it is, I read it is, i saw no proof though. Not in my text anyway, also couldn't find it on google.

Write 1/4 in ternary.
 
...and already know how to characterize the Cantor set in terms of ternary expansions...
