Fortnightly links (89)

The last edition of fortnightly links was more an edition of monthly links it turns out, but we are back in business now.

• Matteo Altavilla, Marin Petkovic, Franco Rota: Moduli spaces on the Kuznetsov component of Fano threefolds of index 2 (im)proves a categorical Torelli theorem for the Kuznetsov component in the del Pezzo 3-fold of degree 2, by explaining the geometry of moduli spaces of Bridgeland-stable objects in the Kuznetsov component.

• Michael Wong: Dimer models and Hochschild cohomology is a really interesting preprint, and its preliminaries are a very good introduction to the theory of dimer models. Highly recommended reading.

• Pamela E. Harris, Marissa Loving, Juan Ramirez, Joseph Rennie, Gordon Rojas Kirby, Eduardo Torres Davila, Fabrice O. Ulysse: Visualizing the support of Kostant's weight multiplicity formula for the rank two Lie algebras contains some marvellous visualisations of weight multiplicities for representations of $\mathfrak{sl}_3$, $\mathfrak{so}_4$, $\mathfrak{so}_5$, $\mathfrak{sp}_4$ and $\mathfrak{g}_2$.
