Description

This lecture introduces CW complexes as spaces constructed by attaching cells to a space X. It explains the process of constructing open neighborhoods for each cell, ensuring the space is normal and Hausdorff. The lecture demonstrates that CW complexes are normal and Hausdorff by showing that disjoint closed sets have disjoint open neighborhoods.
