General Mneimneh-type Binomial Sum involving Harmonic Numbers
Recently, Mneimneh proved the remarkable identity \begin{align*} \sum_{k=0}^n H_k\binom{n}{k} p^k(1-p)^{n-k}=\sum_{i=1}^n \frac{1-(1-p)^i}{i}\quad (p\in [0,1]) \end{align*} as the main result of a 2023 \emph{Discrete Mathematics} paper, where $H_k:=\sum\nolimits_{i=1}^k 1/i$ is the classical $k$-th harmonic number. Thereafter, Campbell provided several other proofs of Mneimneh's formula as above in a note published in \emph{Discrete Mathematics} in 2023. Moreover, Campbell also considered how M…

Hodge-Chern classes and strata-effectivity in tautological rings
Given a connected, reductive $\mathbf{F}_p$-group $G$, a cocharacter $μ\in X_*(G)$ and a smooth zip period map $ζ:X \to \mathop{\text{$G$-{\tt Zip}}}\nolimits^μ$, we study which classes in the Wedhorn-Ziegler tautological rings $T^*(X), T^*(Y)$ of $X$ and its flag space $Y \to G-ZipFlag^μ$ are \textit{strata-effective}, meaning that they are non-negative rational linear combinations of pullbacks of classes of zip (flag) strata closures. Two special cases are: (1) When $X=G\text{-Zip}^μ$ an…

Hitzewellen schon 2024: Studie sagt dramatische Wetteranomalien für Europa voraus
Schmelzwasser ins Grönland soll nach einer Studie schon in diesem Jahr in Südeuropa für extrem heißes Wetter sorgen. Aber auch Deutschland ist bald betroffen.

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.
