In mathematics, there are many senses in which a sequence or a series is said to be convergent. This article describes various modes (senses or species) of convergence in the settings where they are defined. For a list of modes of convergence, see Modes of convergence (annotated index)
Each of the following objects is a special case of the types preceding it: sets, topological spaces, uniform spaces, topological abelian group, normed spaces, Euclidean spaces, and the real/complex numbers. Also, any metric space is a uniform space.
