Classify each set as open, closed, or neither closed nor open. Use Heine-Borel theorem to determine whether it is a compact subset of R.

1. The Cantor set is one of the most famous sets in mathematics and has some rather unique properties. The Cantor set was discovered in 1874 by Henry John Stephen Smith and introduced to the world by George Cantor in 1883. The Cantor set is a set of points lying on a single closed line segment, say from [0,1]. It is constructed as follows: Start with the closed interval Co-10.1]. Remove the open...

plz use the definition solve the question
Definition 1. Given a set A CR, an elementu ER is an interior point of A if there exists an e > 0 such that (x - 5,3 +E) CA. The interior of A is the set Aº consisting of all interior points of A. A set A is called open if A= A'. Definition 2. Given a set A CR, an element X ER is a limit point of A if for...

1. Prove that for any set S S R, S is closed if and only if Se is open. Notice the book has a proof of this, but it uses a different notation for set complements and a different definition of neighborhood. You may consult it, but you must write your proof using the definition for interior point I presented in class (also in the notes on blackboard). If you copy the proof from the book you will not receive...
