On the Chromatic Number of Stable Kneser Hypergraphs: Verifying the Conjecture for New Families
One of the key unsolved conjectures in hypergraph coloring is about the chromatic number of $s$-stable $r$-uniform Kneser hypergraphs $\mathrm{KG}^r(n,k)_{s\textup{-stab}}$. The problem remains largely open, particularly in the case where $s > r\geq 3$. To the best of our knowledge, no information is available except a limited number of computations conducted for the instances when $r=3, 4$, $s=4, 5$, $k=2,3$ with some $n$ does not exceed 14. In this study, we verify the conjecture for infinity…

Photo of the week: Autumn in the garden
Ich bleibe beim herbstlichen Thema. Hier ist der wilde Wein (der vermutlich kein wilder Wein, sondern ein anderes Rankgewächs ist) erst dabei, sich rot zu verfärben. Heute strahlt die ganze hintere Gartenecke in leuchtendem Rot. Sonnige Oktobertage sind mit das beste am Jahr.

Please stop spreading FUD about people who are suffering through genocide and famine for whom Mastodon and the fediverse are often their last lifeline.
You are not helping.
Scam accounts are very easy to detect as they usually employ bots and have multiple automatically-created accounts on different servers.
And for the others, we are doing our best to protect the people from Gaza who have Mastodon accounts on the fediverse from scammers with initiatives like

Gaza Verified
I’ve personally had video conversations on Signal with the people from Gaza whose Mastodon accounts on the fediverse are listed here and I verify that their accounts are genuine. – Aral Balkan

Flip side of this: ~3 years ago, I got automated calls from “RBC Visa”. I ignored them.
Then my card stopped working.
So I called the number on the back of my card and said as much.
The agent gave me a hard time: “So you JUST IGNORED our calls about this?”
“No; I didn’t know they were you calling.”
“How did you not know they were us?! It says ‘this is RBC Visa’ when you answer!”
“That’s indistinguishable from fraud.”
He did not like that. He thought …

Neuer Digitalminister Wildberger bekommt 4,47 Mrd. Euro. Doch wie viel davon fließt in echte digitale Souveränität – etwa in OpenDesk von ZenDiS, die freie Office-Alternative zu Microsoft? Milliardenetat schön und gut – aber was nützt er, wenn am Ende wieder nur Lizenzen verlängert werden?

Erstmals verfügt das Digitalressort über einen eigenen Finanzplan. Der Breitbandausbau wird mit 2,3 Milliarden, die IT-Infrastruktur mit knapp einer gefördert.

Criminals posing as US immigration officers have carried out robberies, kidnappings, and sexual assaults in several states,

The bureau urges agencies to ensure officers clearly identify themselves and to cooperate when civilians ask to verify an officer’s identity—including by allowing calls to a local police precinct

FBI Warns of Criminals Posing as ICE, Urges Agents to ID Themselves
In a bulletin to law enforcement agencies, the FBI said criminal impersonators are exploiting ICE’s image and urged nationwide coordination to distinguish real operations from fakes.

"We feel accountable to our religious tradition. And just as accountable to our own intuition. When we have a question or a challenge on our religious tradition, we don't abandon our religious tradition, nor do we assume a posture of submission or sacrifice towards our own intution. That is not what the Talmud does, instead, we think harder, think more critically, think more carefully." Sammanfattar bra min syn på bibeltolkning och vrf Talmud är ett så storslaget dokument

R. Aviva Richman: Why Talmud is the Bedrock of My Faith - Ta Shma
The Talmud has often been subject to misrepresentation—viewed as esoteric or overly complex—yet it holds profound power as a centerpiece of Jewish tradition. How can Talmud and Talmud study anchor an approach to Judaism that speaks to the challenges  and dangers of our moment? How can its embrace of complexity, argument, and multivocality offer a model for living a thoughtful and principled Jewish life in our uncertain times?  Source sheet: https://mechonhadar.s3.us-east-1.amazonaws.com/…

Improved Bounds for the Index Conjecture in Zero-Sum Theory

Improved Bounds for the Index Conjecture in Zero-Sum Theory
The Index Conjecture in zero-sum theory states that when $n$ is coprime to $6$ and $k$ equals $4$, every minimal zero-sum sequence of length $k$ modulo $n$ has index $1$. While other values of $(k,n)$ have been studied thoroughly in the last 30 years, it is only recently that the conjecture has been proven for $n>10^{20}$. In this paper, we prove that said upper bound can be reduced to $4.6\cdot10^{13}$, and lower under certain coprimality conditions. Further, we verify the conjecture for $n<1.…
