  • Yukinobu Toda: Derived categories of Quot schemes of zero-dimensional quotients on curves gives the semiorthogonal decompositions predicted by the Bagnarol–Fantechi–Perroni formula for the class of $\mathrm{Quot}_C(\mathcal{E},d)$ in the Grothendieck ring of varieties (which you can play with using the Hodge diamond cutter, see the corresponding blog post). Cool! The methods are really interesting too.

  • David Chanin: Introducing Mathlib Changelog introduces mathlib-changelog.org, a beautiful change log for mathlib, where you can search how your favourite objects and results have been evolving.

  • Mina Aganagic: Homological Knot Invariants from Mirror Symmetry is a paper for the ICM proceedings, discussing a homological mirror symmetry point-of-view on knot invariants, using equivariant mirror symmetry for hyperkähler varieties. Highly recommended reading in conjunction with Catharina's ICM paper from the previous fortnightly links.
