Reduction principles for proper actions
We study the core of a proper action by a Lie group $G$ on a smooth manifold $M$, extending the construction for $G$ compact by Skjelbred and Straume. Moreover, we show that many properties of a proper $G$-action on $M$ are determined by the action of a group $G'$ on the corresponding core $_cM$. We say that such properties admit a reduction principle. In particular, we prove that a proper isometric $G$-action on $M$ is polar (resp. hyperpolar) if and only if the $G'$-action on $_cM$ is polar (…

Escalating the friction between Washington and one of its closest allies in Latin America,
Donald Trump said Sunday, the United States will slash assistance to Colombia because its leader, Gustavo Petro,
“does nothing to stop” drug production"
The U.S. president warned that Petro “better close up” drug operations “or the United States will close them up for him, and it won’t be done nicely.”
Hours later, Defense Secretary Pete Hegseth announced the latest U.S. strik…

Trump announces an end to US aid to Colombia
It's a war of words between President Donald Trump and Colombian leader Gustavo Petro over illegal drugs, with hundreds of millions of dollars in American aid hanging in the balance. Trump says he'll slash U.S. assistance and enact tariffs because Colombia's leftist president “does nothing to stop” drug production and is an “illegal drug leader.” Petro is rejecting the accusations and defending his work to fight narcotics in Colombia, the world’s largest exporter of cocaine. Colombia …

Wir dürfen nicht zulassen, dass Menschen im Verkehr getötet werden.
Mängel in der Gestaltung der Infrastruktur sind fast immer ursächlich, wenn Menschen getötet werden. Spätestens wenn es zu Opfern kommt, werden diese Mängel erkennbar. Diese Möglichkeit sie zu beseitigen, muss genutzt werden, bevor weitere Menschen getötet werden.
Häufen sich Kollisionen, muss man fragen, ob die Straßenverkehrsbehörde ihrer Sorgfaltspflicht gerecht wird.

Attached: 3 images In #Wiesbaden wurde heute ein #Ghostbike als Mahnmal und Gedenkstätte für eine getötete Radfahrerin aufgestellt, nur wenige Meter neben einem schon vorhandenen weißen Fahrrad. Dass Menschen plötzlich aus ihren Familien, Freundeskreisen und Arbeitsumfeld gerissen werden, ist trauriger Alltag in Deutschland - aber vermeidbar! Wir fordern daher für ganz Hessen den Ausbau sicherer Radinfrastruktur, mehr Polizeikontrollen und Geschwindigkeitsreduzierung zur Unfallvermeidun…

False choice (with a value judgment in its wording).
You can, & should, continue to raise demonstrable & valid concerns about the accessibility of LLM output and _also_ consider if (or how) you can improve it (he offers options).
But no free labor from me.
