A: Tag management 2021

Rodrigo de AzevedoGiven the existence of tags matlab and python the rising popularity of Julia the fact that Julia is free (unlike MATLAB) I propose the creation of tag julia for mathematical questions that contain Julia code. At the moment, searching for julia leads mostly to questions on Julia sets.

Julia is a high-level, high-performance, dynamic programming language. While it is a general-purpose language and can be used to write any application, many of its features are well suited for numerical analysis and computational science.Distinctive aspects of Julia's design include a type system with parametric polymorphism in a dynamic programming language; with multiple dispatch as its core programming paradigm. Julia supports concurrent, (composable) parallel and distributed computing (with or without using MPI and/or the built-in corresponding to "OpenMP-style" threads), and direct calling...

Q: Reference: Covariance operator is compact

G. ChiusoleI am looking for a reference for the following theorem: Let $(X,\Vert \cdot \Vert)$ be a separable Banach space and $C: X^{\ast} \rightarrow X \subseteq X^{\ast \ast}, f \mapsto \int_X f(x) \cdot - ~ d\mu(x) =: q(f, -)$ be the covariance operator of a Gaussian measure on $X$. Then $X$ is compact...

In mathematics, Gaussian measure is a Borel measure on finite-dimensional Euclidean space Rn, closely related to the normal distribution in statistics. There is also a generalization to infinite-dimensional spaces. Gaussian measures are named after the German mathematician Carl Friedrich Gauss. One reason why Gaussian measures are so ubiquitous in probability theory is the central limit theorem. Loosely speaking, it states that if a random variable X is obtained by summing a large number N of independent random variables of order 1, then X is of order...
17 hours ago, by Arctic Char
A new tag was created and removed (by me here and here).
The current revision of the tag-excerpt for :
> About measures on infinite-dimensional topological vector spaces for which every continuous linear functional is Gaussian. Also in conjunction with abstract Wiener spaces and Gaussian processes.

Maybe there should be on meta. (Or some other reasonable tag name for this topic.) There are questions such as: Privilege page on reduced ads doesn't show on this site, even though there are now advertisements or What does the “see reduced ads” privilege mean?
And I have recently asked this one: Are there ads on Mathematics Stack Exchange?
