I think it’s more important than ever that we fund a plurality of implementations of the “twitter-like” Fediverse.
I have a nagging suspicion that Mastodon will fall victim to the embrace, extend, extinguish action of some major corporation or VC money rather soon. It is clearly the most valuable platform with the greatest number of users today, and has obvious points of failure (Eugen’s corporation being the primary one). The best defense is to have multiple strong, popular implementa…

Reduced Products of Collapsing Algebras
$\mathop{\rm rp}\nolimits ({\mathbb B})$ denotes the reduced power ${\mathbb B}^ω/Φ$ of a Boolean algebra ${\mathbb B}$, where $Φ$ is the Fréchet filter $Φ$ on $ω$. We investigate iterated reduced powers ($\mathop{\rm rp}\nolimits ^0 ({\mathbb B})={\mathbb B}$ and $\mathop{\rm rp}\nolimits ^{n+1} ({\mathbb B} )=\mathop{\rm rp}\nolimits (\mathop{\rm rp}\nolimits ^n ({\mathbb B}))$) of collapsing algebras and our main intention is to classify the algebras $\mathop{\rm rp}\nolimits ^n (\math…

Folge für die Suche nach außerirdischem Leben: Erdmagnetfeld älter als gedacht
In Grönland gefundene Steine wurden schon vor 3,7 Milliarden Jahren magnetisiert. Das hätte auch Folgen für die Suche nach außerirdischem Leben.

On $1/2$ estimate for global Newlander-Nirenberg theorem
Given a formally integrable almost complex structure $X$ defined on the closure of a bounded domain $D \subset \mathbb C^n$, and provided that $X$ is sufficiently close to the standard complex structure, the global Newlander-Nirenberg problem asks whether there exists a global diffeomorphism defined on $\overline D$ that transforms $X$ into the standard complex structure, under certain geometric and regularity assumptions on $D$. In this paper we prove a quantitative result of this problem. Ass…

Bordism of flow modules and exact Lagrangians
For a stably framed Liouville manifold X , we construct a "Donaldson-Fukaya category over the sphere spectrum" F(X; S). The objects are closed exact Lagrangians whose Gauss maps are nullhomotopic compatibly with the ambient stable framing, and the morphisms are bordism classes of framed flow modules over Lagrangian Floer flow categories; this is enriched in modules over the framed bordism ring. We develop an obstruction theory for lifting quasi-isomorphisms in the usual Fukaya category to quasi…

Hands up if you think public EU money being awarded by @… / @… should be subject to a transparent process where we can see all internal discussions/comments/reasoning concerning funding decisions including who made them.

På året Venedig-biennale med temaet "Foreigners Everywhere" er det for fŸrste gang en grŸnlandsk kunster, fotografen Inuuteq Storch, der udstiller på den danske pavillon.
Det overrasker mig lidt,
1) at det ikke er sket fŸr.
2) at den grŸnlandske kulturminister havde ikke mulighed for at deltage i åbningen [ifŸlge Weekendavisen [$];

Nogens menneske
Kalaallit Nunaat. Inuuteq Storch er den første grønlandske kunstner, der udstiller i den danske pavillon på Venedig-biennalen. Venner, familie, landskab og længsel efter landets spirituelle fortid optager den ellers helt nutidige 35-årige fotograf.
