We run our script every day (it uses the StackExchangeAPI to get all posts changed since the last run). It takes a few days until the links appear on zbmath.org. If some links have not been picked up for trackbacks it might be due to a bug in our script. Could you give me an example for such a comment? — Isabel Beckenbach 20 hours ago

There are 30 comments of mine that were not picked up for trackbacks. These are: [1], [2], [3], [4], [5], [6], [7], [8], [9], ... — The Amplitwist 6 mins ago

... [10], [11], [12], [13], [14], [15], [16], [17], [18], [19], ... — The Amplitwist 5 mins ago

... [20], [21], [22], [23], [24], [25], [26], [27], [28], [29], ... — The Amplitwist 4 mins ago

... [30]. (Also, some comments of mine were picked up for trackbacks, but they do not look any different from many of these examples in terms of the formatting of the zbMATH review links.) — The Amplitwist 3 mins ago

Q: The meaning of random number generator test failing

I have a random number generator (number theoretic) that passes all of the NIST tests except the random excursions test. Is there any deep dark meaning to this? To amplify "deep dark meaning", are there other number-theoretic sort-of-random function with the same property (as suggested by @LSpice...

Rng (algebra)

In mathematics, and more specifically in abstract algebra, a rng (or non-unital ring or pseudo-ring) is an algebraic structure satisfying the same properties as a ring, but without assuming the existence of a multiplicative identity. The term rng (IPA: ) is meant to suggest that it is a ring without i, that is, without the requirement for an identity element. There is no consensus in the community as to whether the existence of a multiplicative identity must be one of the ring axioms (see Ring (mathematics) § History). The term rng was coined to alleviate this ambiguity when people want to refer...

Q: Are quivers useful outside of Representation Theory?

There is a trend, for some people, to study representations of quivers. The setting of the problem is undoubtedly natural, but representations of quivers are present in the literature for already >40 years. Are there any connections of this trend with other Maths? For, it seems like it is a self-...
