Multiplicative Hitchin fibrations and Langlands duality
We identify pairs of (twisted) multiplicative Hitchin fibrations which are "dual" in the sense that their bases are identified and their generic fibres are dual Beilinson $1$-motives. More precisely, we match the following: (1) an untwisted multiplicative Hitchin fibration associated with a simply-laced semisimple group $G$ with an untwisted multiplicative Hitchin fibration associated with the Langlands dual group $G^\vee$; (2) a twisted multiplicative Hitchin fibration associated with a simply…

Natuurlijk heeft D66 ook nog werk te doen maar komt in ieder geval redelijk uit de analyse. En reageert er in ieder geval niet zo giftig op als de VVD.

Colossus, with deeply reported profiles of tech and business moguls, is a magazine where "punches will be pulled, but the reading pleasure isn't sacrificed" (Hiten Samtani/@hitsamty)

The team at Colossus is breaking something in magazine journalism in a fascinating way. Let me try to articulate. Even just a few years ago, if you wanted to read a beautifully written, exhaustively reported and actually interesting piece on someone shaping a corner of the

Demostart des heutigen Klimastreiks in Freiburg doch voller als gedacht. Davor (mit etwas Verspätung - und zu hundert oder so) mit dem Rad zur Demo.

Jakten på friidrottens äldsta världsrekord: ”Finns en anledning till att det stått sig”
Jarmila Kratochvilovas världsrekord på 800 meter har stått sig sedan 1983. Men inför VM i Tokyo hotar brittiskan Keely Hodgkinson nu ”det omöjliga rekordet”.

From Hitchin Systems to Rational Elliptic Surfaces with C*-actions via Orbifold Hilbert Schemes
Using orbifold Hilbert schemes, we compactify all two-dimensional Hitchin systems corresponding to types A0-tilde, D4-tilde, E6-tilde, E7-tilde, and E8-tilde, thereby obtaining four rational elliptic surfaces with C*-actions. Their singular fibers and relative minimal models are listed in the main table. To this end, we prove that Hilbert schemes of orbifold surfaces are connected smooth projective schemes under suitable conditions, and we use the Hilbert-Chow morphism to construct the minimal …
