Two from Casselman's "A companion to Macdonald's book on p-adic spherical functions": The word ‘´epingler’ means ‘to pin’, and the image that comes to mind most appropriately is that of a mounted butterfly specimen. [Kottwitz:1984] uses ‘splitting’ for what most call ‘´epinglage’, b...

Diaconis and Efron wrote a paper "Testing for Independence in a Two-Way Table: New Interpretations of the Chi-Square Statistic" that was followed by 10 papers discussing their suggestion. The following is from Diaconis and Efron's rejoiner: The critical paper that they refer to starts with a s...

Let $X$ be a set and $(T,\cdot)$ an abelian group. Is there a category of $T$-dynamical systems on $X$ which yields useful information about $X$ and $T$? More precisely, is there a category whose objects are dynamical systems, i.e., $\phi:X \times T \to X$ such that $\phi(x,t + s) = \phi(\phi(x,...

This question from March 2020 points out that many questions/answers link to papers at the http://front.math.ucdavis.edu/ frontend instead of at the arXiv itself, but that the frontend had been down a few weeks. There are c.600 affected questions and it looks like a large proportion of the links...

At this moment, it is unclear whether a project like this should be done. (After all, until we heard from people running the arXiv frontend, we still should count as a possibility that it will be running again at some point.) Still, it might be useful to analyze a bit what would the scope of the ...
