Example 1: Proving a Space is Compact
Problem: Show that a closed and bounded subset of Euclidean space \(\mathbb{R}^n\) is
compact. Solution Outline: 1. Recall the Heine-Borel theorem states that in
\(\mathbb{R}^n\), a subset is compact if and only if it is closed and bounded. 2. Step 1:
Confirm that the subset is closed (given). 3. Step 2: Confirm that the subset is bounded
(given). 4. Step 3: Apply the Heine-Borel theorem directly, concluding the set is compact.
Key Takeaways: - The importance of the theorem - How to verify the conditions in practice

Example 2: Showing a Space is Hausdorff
Problem: Prove that the product of two Hausdorff spaces is Hausdorff. Solution Outline: 1.
Recall that a space is Hausdorff (T2) if any two distinct points have disjoint
neighborhoods. 2. Step 1: Take two distinct points in the product space \(X \times Y\). 3.
Step 2: Since the points are distinct, either their \(X\)-coordinates differ or their \(Y\)-
coordinates differ. 4. Step 3: Use the Hausdorff property of \(X\) or \(Y\) to find disjoint
3
neighborhoods around these points. 5. Step 4: Construct open neighborhoods in the
product space as the product of the neighborhoods in the factors. 6. Conclusion: The
product space is Hausdorff. Key Insight: - The product of T2 spaces remains T2, a vital
property in topology.
