    Cantor Form Set

SUMMARY

The discussion centers on the Cantor set C in ternary form with a factor of 1/n, where n is greater than or equal to 2. The original poster, Cbarker1, seeks clarification on whether to multiply the Cantor set by 1/n or interpret it differently. Participants suggest that the notation 1/n C could be ambiguous and recommend rephrasing for clarity. They also explain the iterative process of constructing the Cantor set by removing segments, emphasizing the need for precise notation to avoid confusion.

PREREQUISITES
  • Understanding of Cantor set construction
  • Familiarity with ternary (base-3) number system
  • Basic knowledge of mathematical notation and LaTeX
  • Concept of iterative processes in set theory
NEXT STEPS
  • Research the construction of the Cantor set in detail
  • Learn about the implications of scaling sets by factors like 1/n
  • Explore mathematical notation clarity, especially in LaTeX
  • Investigate the properties of sets under iterative deletions
USEFUL FOR

Mathematicians, students studying set theory, and anyone interested in the properties and constructions of Cantor sets.

TL;DR
I am trying to comprehend the Cantor set C with a 1/n factor in base 3
Dear Everybody,

I am confused by ##1/n C##, where C is a cantor set in base 3 and ##n\geq2##. I can understand the construction of the normal Cantor set.

How do I comprehend this set with this extra condition. Do I multiply the set with ##1/n## or not?

Thanks,
Cbarker1

mentor note: adjusted latex to use double # instead of single #

Understanding Cantor set C in Tetany form with 1/n factor in front C
I have never seen the word "Tetany" before: do you mean "ternery"? Even with this correction I'm afraid the rest of the post doesn't make much sense to me.

Do you have a reference for the ideas you are talking about?

If not, can you provide a more complete description of the set avoiding ambiguous notation like ##1/n C## which whether in ## \LaTeX ## or plain text can mean either ## \frac{1}{nC} ## or ## \frac{1}{n}C ##. Perhaps you could start by rephrasing "The Cantor ternary set is created by iteratively deleting parts of a set of line segments. One starts by deleting the open middle third ## \left ( \frac{1}{3} , \frac{2}{3} \right) ## from the interval ## [ 0 , 1 ] ##."

I changed "tetany" in the thread title to "ternary," as my best guess as to what the OP was trying to convey.

Also, perhaps the "1/nC" (with same complaint about what 1/nC actually means) is meant to convey the level of middle third deletions. Again, that's a guess. If so, with n = 1, we would have the two subintervals [0, .1] and [.2, 1], using base-3 fractions. With n =2, we remove the middle third from each of the two previously listed subintervals. This would produce four subintervals: [0, .01], [.02, .1], [.2, .21], and [.22, 1], again using base-3 fractions.

And so on.

your guesses are right. I want that word Ternary and ##(1/n)*C##.
 
OK, so how much of the set do you remove at the first iteration?

How much at the second?
...
How much at the ## n ##th?
...

How much in total as ## n \to \infty ##?
