I don’t actually know much about topology, apart from the edge-case of graph theory. Often the coarse topology of networks is of interest, or the more metaphorical knowledge topology, or actual continuous fields or knots or whatever. Sometimes I care about the induced topology of a metric convergence, but this is hardly fancy stuff.
Apparently grown-up topology has applications too? See for example
- Topology of trees and freaky Gaussian maps OMG
- Persistent homology in adversarial learning references
