Proposal: Merge probability and probability-theory tags. The idea behind having two tags is to divide basic and advanced probability questions, but it does not work and I believe it couldn't work. It is better to have single probability tag and use additional tags like combinatorics, measure-the...
In his book, Information Geometry and its Applications, p. 28, Amari makes a statement without proof (quoted in the form of an image below) that seems to be incorrect. I would like to know whether the claim is wrong, or if I have understood it incorrectly. If I've misunderstood it, I'd like to kn...
While reading (No need to go see the paper) this paper, I felt like Theorem 8 may be provable more easily without using barycenters of extreme points of some sets of measures. Let $f$ be a convex function on $(0,\infty)$ such that $f(1)=0$ and for two measures $P$ and $Q$ on the same measurable ...
Please create the tag "realizability" for questions regarding realizability as the term is used by researchers like Kleene, Kreisel, Troelstra and also in more modern work. This would be rather useful because the term is sometimes used in completely different contexts, so having a well-defined ta...
In the past week or so, I edited the tag-wiki for ENT to make it far less wishy-washy that primitive roots and quadratic residues were NT and everything before that in a typical class or textbook are ENT. (It's not quite easy vs. non-easy. For instance, Pythagorean triples are the solutions to a...
The tags elementary-number-theory and number-theory have been recently mentioned in this question: There are 1,732 questions tagged both elementary-number-theory and number-theory However, in that question these two tags serve only as an illustration of a more general issue. In this post I'd like...
