The MRI at Iceland's biggest hospital Landspítalinn is broken at the moment.
A scrubber that cleaning personal brought into the room is now stuck inside. 😂
Repairs are under way

Sufficient minimum degree conditions for the existence of highly connected or edge-connected subgraphs
Mader conjectured that an average degree of at least $3k-1$ is sufficient for the existence of a $(k+1)$-connected subgraph. The following minimum degree version holds: Every graph with minimum degree at least $3k-1$ has a $(k+1)$-connected subgraph on more than $2k$ vertices. Moreover, for triangle-free graphs, already an average degree of at least $2k$ is sufficient for a $(k+1)$-connected subgraph (which has at least $2(k+1)$ vertices). For edge-connectedness (in simple graphs), we prove t…

Additive Approximation Schemes for Low-Dimensional Embeddings
We consider the task of fitting low-dimensional embeddings to high-dimensional data. In particular, we study the $k$-Euclidean Metric Violation problem ($\textsf{$k$-EMV}$), where the input is $D \in \mathbb{R}^{\binom{n}{2}}_{\geq 0}$ and the goal is to find the closest vector $X \in \mathbb{M}_{k}$, where $\mathbb{M}_k \subset \mathbb{R}^{\binom{n}{2}}_{\geq 0}$ is the set of all $k$-dimensional Euclidean metrics on $n$ points, and closeness is formulated as the following optimization problem…

Asymptotic properties of zeros of Riemann zeta function
We try to define the sequence of zeros of the Riemann zeta function by an intrinsic property. Let $(z_k)_{k\in \mathbb{N}}$ be the sequence of nontrivial zeros of $ζ(s)$ with positive imaginary part. We write $z_k= 1/2+iτ_k$ (RH says that these $τ_k$ are all real). Then the sequence $(τ_k)_{k\in \mathbb{N}},$ satisfies the following asymptotic relation \[\sum_{k\in\mathbb{N}}\frac{2x}{x^2+τ_k^2}\simeq \frac12\log\frac{x}{2π}+\sum_{n=1}^\infty \frac{a_n}{x^n},\,\,x\to +\infty\] where $a_{2…

Splittings in a complete local ring and decomposition its group of units
Let $(R,M,k)$ be a complete local ring (not necessarily Noetherian). Then we prove that the natural surjective ring map $R\rightarrow k$ admits a splitting if and only if $\Char(R)=\Char(k)$. In addition, if $\Char(R)\neq\Char(k)$, then we prove that the natural surjective map between the groups of units $R^{\ast}\rightarrow k^{\ast}$ admits a splitting. As an application of this theorem, we show that the following short exact sequence of Abelian groups: $$\xymatrix{1\ar[r]&1+M\ar[r]& R^{\ast}\…

Trump is recklessly shredding our economic advantages in the global economy.
Companies that are looking to make investments shouldn’t have to worry if Trump has cooked the books on economic data--but that’s exactly what’s happening following his decision.

Firing of labor statistics head undermines trust in key data, ex-Trump official warns
President Trump is expected to nominate a new head of the Bureau of Labor Statistics this week, days after firing Commissioner Erika McEntarfer following the release of a disappointing jobs report. The president dismissed the data as “rigged” and “manipulated for political purposes.” Geoff Bennett discussed more with William Beach, the commissioner of labor statistics during the first Trump term.
