These notes are written to accompany the lecture course ‘Introduction to Algebraic Topology ’ that was taught to advanced high school students during the Ross Mathematics Program in Columbus, Ohio from July 15th-19th, 2019. Made for sharing. The sets belonging to T are usually called the open subsets of X(with respect to T ). Topology provides the most general setting in which we can talk about continuity, which is good because continuous functions are amazing things to have available. 22 2.3.
