The Cantor Set

The Cantor set is important for understanding Topology (open and closed sets) and measure.

Cantor set

Let C0 be the closed interval [0,1] and define C1 to be the set that results when the open middle third is removed:

[C1=C0?=??]

This process continued gives us the Cantor set:

C=n=0Cn
Or alternatively:
[C=[0,1]((13,23)(?,?)(?,?)...) ]


Properties of the Cantor set

Below are some properties of the Cantor set, with explanations on the reverse side.

The cantor set...

  • has [zero/finite/infinite] measure
  • is [countably/uncountably] infinite
  • has dimension of [...]
  • is [open/closed/neither/both]
  • is [compact/not compact]
  • is [perfect/not perfect]
  • is [...] dense
