arxiv_authors: Arxiv authors (1993-2003)
Scientific collaborations between authors of papers submitted to arxiv.org, under 5 categories: gr-qc, astro-ph, cond-mat, hep-ph, and hep-th categories, spanning January 1993 to April 2003. If an author i co-authored a paper with author j, the graph contains a undirected edge from i to j. If the paper is co-authored by k authors this generates a completely connected (sub)graph on k nodes.
This network has 108300 nodes and 186936 edges.

$k$-graph algebras are iterated Cuntz-Pimsner algebras -- from the bottom up

Abstract: We introduce a new method of expressing a $k$-graph $C^*$-algebra as a Cuntz-Pimsner algebra. Kumjian, Pask, and Sims have done this directly, using a linking algebra approach and a $(k-1)$-graph algebra. This can be iterated downward. Our process, on the other hand, starts at the bottom, with Pimsner's theorem for graph algebras, and iterates upward. We actually work with product systems over $\mathbb N^k$, and the result for $k$-graphs is a special case. Our iteration step involves a ``decategorization'' of a recent theorem showing that the Cuntz-Pimsner construction is functorial at the level of ``enchilada categories''.

A little work done on my web browser. I'm working on bookmarks, and instead of storing them in a text file like I originally planned I'm going to try out storing them in an sqlite database. Some of that infrastructure is in place. Bookmarks are going to be tag based rather than in folders, so you can tag a bookmark with multiple categories and it will show up in all of them. I think that's a better way of organizing them than the traditional folder view.

Enhanced left triangulated categories

Abstract: In this short note, we study dg categories with homotopy kernels, whose homotopy categories are known to admit a natural left triangulated structure. Prototypical examples of such dg categories arise as dg quotients of exact dg categories. We demonstrate that the stablization of the homotopy category of such a dg category admits a canonical dg enhancement via its bounded derived dg category.

Watched a couple of episodes of #DeArktiskeReddere on DR (public broadcaster on Denmark) yesterday (series about #Greenland's search and rescue team - though they do a lot of emergency air ambulance type work too).
It's a really gripping and well filmed piece of work, sensitive on the difficult topics too and shows really well how different authorities work together.
I imagine it would be uncomfortable watching for USians who seem to imagine some kind of stone age society seeing healthcare emergencies dealt with so professionally with such excellent equipment (and for free at point of delivery).
I also find it hard to explain that the categories and separation between "Danes" and "Greenlanders" isn't always so clear cut and I think the programme got that over well.
It's filmed mostly in Danish but with Swedish, Norwegian and quite a bit of English, so may not travel easily but it's a really well done piece of TV and if you are at all interested in Greenland, it's worth seeking out.

Higher algebra in $t$-structured tensor triangulated $\infty$-categories

Abstract: We generalize fundamental notions of higher algebra, traditionally developed within the $\infty$-category of spectra, to the broader setting of $t$-structured tensor triangulated $\infty$-categories ($ttt$-$\infty$-categories). Under a natural structural condition, which we call "projective rigidity", we establish higher categorical analogues of Lazard's theorem and prove the existence and universal property of Cohn localizations. Furthermore, we generalize higher almost ring theory to the $ttt$-$\infty$-categorical setting, showing that $\pi_0$-epimorphic idempotent algebras are in natural bijection with idempotent ideals. By exploiting deformation theory, we establish a general \'etale rigidity theorem, proving that the $\infty$-category of \'etale algebras over a fixed connective base is completely determined by its discrete counterpart. Finally, we characterize the moduli of such projectively rigid $ttt$-$\infty$-categories, demonstrating that the presheaf $\infty$-category on the 1-dimensional framed cobordism $\infty$-category serves as the universal projectively rigid $ttt$-$\infty$-category.
