Tags
A tag is a keyword or label that categorizes your question with other, similar questions.
Intended for questions about convexity spaces: metrizable convexities; convex sets; convex hulls; convexity preserving functions; convex isomorphisms; separation axioms (S1, S2, S3, S4), interval convexities; basis of convexities and topics alike. When considering convex sets in vector spaces, please use the [convex-analysis] tag.

Graph limits are the study of graphons, the compactification of the set of finite simple undirected graphs. This tag does NOT refer to limits of functions drawn pictorially in the plane.
Use this tag in conjunction with [tag:graph-theory] if your question is about graphons or graph limits.

The Wiener algebra, usually denoted by $A(\mathbb{T})$, is the space of absolutely convergent Fourier series. Here $\mathbb{T}$ denotes the circle group. The norm of a function $f \in A(\mathbb{T})$ is $\|f\| = \sum\limits_{n = - \infty}^\infty |\hat{f}(n)|$.
