Topology,The language of spectral theory may be algebra, but its environment is .. Topology on the one hand underlies geometry; for us it is more relevant that it also underlies the theory of limits and analysis.眼界 发表于 2025-3-26 01:43:17
Topological Algebra,When the same set carries both algebraic and topological structure then it is good if they are “compatible”: this usually means that the algebraic operations are continuous.anniversary 发表于 2025-3-26 05:29:05
