Welcome! This is one of over 2,200 courses on OCW. In general, topology is the rigorous development of ideas related to concepts such nearness, neighbourhood, and convergence. How many smooth structures? Lecture Notes. Math GU4053: Algebraic Topology Columbia University Spring 2020 Instructor: Oleg Lazarev (olazarev@math.columbia.edu) Time and Place: Tuesday and Thursday: 2:40 pm - 3:55 pm in Math 307 Office hours: Tuesday 4:30 pm-6:30 pm, Math 307A (next door to lecture room). 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. The sets belonging to T are usually called the open subsets of X(with respect to T ). They focus on how the mathematics is applied, in the context of particle physics and condensed matter, with little emphasis on rigorous proofs. during winter semester 2005 and summer semester 2006. We will also apply these concepts to surfaces such as the torus, the Klein bottle, and the Moebius band. a topology on X. ∅,{b},{a,b} 4. Metric Spaces 1.1.
