Habe immer davon gesprochen, im Garten mal eine Reineclaude zu pflanzen, aber wie üblich nie gehandelt.
Jetzt waren die Nachbarn schneller! 🥰
Ob das noch etwas wird, bis die Früchte tragen? 🤷‍♂️

Nach einer Woche renovieren, möchte ich sagen: traut Euch an Lehm ran, sieht fantastisch aus auf Wänden und ist super fürs Raumklima. Konkret Z.B. Conluto Flächenspachtel, damit kann man sogar auf Dispersionsfarbe arbeiten. Neue Erkenntnis: Galerieschienen sind eine wirklich gute Erfindung.

On the Complexity of the Skolem Problem at Low Orders
The Skolem Problem asks to determine whether a given linear recurrence sequence (LRS) $\langle u_n \rangle_{n=0}^\infty$ over the integers has a zero term, that is, whether there exists $n$ such that $u_n = 0$. Decidability of the problem is open in general, with the most notable positive result being a decision procedure for LRS of order at most 4. In this paper we consider a bounded version of the Skolem Problem, in which the input consists of an LRS $\langle u_n \rangle_{n=0}^\infty$ and a…

Ja doch, die Hoffnung auf neue Fruchtansätze bei den #Zucchini steigt. Sie werden dicker. 😁
Aber dann muss ich zurückschneiden. Irgendwie nehmen die auch Licht von den #Tomatenpflanzen. Früher standen die

Magic Steady State Production: Non-Hermitian and Stochastic pathways
Universal quantum computers require states with both entanglement and non-stabilizerness, the latter property being commonly known as \textit{quantum magic}. Here, we introduce a protocol that prepares magic steady states by leveraging non-Hermitian dynamics, which, contrary to unitary dynamics, can host pure-state attractors. We investigate the dissipative qubit, in which we find the optimal parameters to prepare $|H\rangle$ and $|T\rangle$ states. Interestingly, this approach does n…

FAUST XXVII: The circumbinary disk and the outflow of the L 1551 IRS 5 binary system
Using continuum and $\text{C}^{18}\text{O}\:(2-1)$ line data obtained from the large ALMA program FAUST, we studied the structure of the protostellar binary system L1551 IRS5 at scales between 30 and 3,000 au to constrain its properties, from the circumstellar and circumbinary disks up to the envelope and outflow scales, which exhibits complex and entangled structures at the scales of its inner and outer envelopes, presumably caused by the influence of the central binary. Assuming a dust-to-gas…

The Miyaoka-Yau inequality for singular varieties with big canonical or anticanonical divisors
We establish the Miyaoka-Yau inequality for $n$-dimensional projective klt varieties with big canonical divisor $K_X$: \[ (2(n+1)\widehat{c}_2(X) - n \widehat{c}_1(X)^2) \cdot \langle c_1(K_X)^{n-2} \rangle \ge 0. \] We also prove the Miyaoka-Yau inequality for K-semistable projective klt varieties with big anticanonical divisor $-K_X$. As part of our approach, we define the non-pluripolar product $\langle α_1 \cdots α_p \rangle$ on singular varieties, and establish the Bogomolov-Gieseker typ…

Kappa Plane Wave Modes and Continuous Squeezing in Quantum Field Theory
We introduce a new family of field modes in flat spacetime -- termed $κ$-plane wave modes -- constructed from $κ$-dependent linear combinations of Minkowski plane waves. These modes define a one-parameter family of vacua, $|0_κ\rangle$, that smoothly interpolate between different quantizations, reducing to the Minkowski vacuum in the limit $κ\to 0$. We show that $|0_κ\rangle$ is uniquely characterized as a continuous-mode squeezed vacuum, with frequency-dependent squeezing parame…

The existence of suitable sets in locally compact strongly topological gyrogroups
A subset $S$ of a topological gyrogroup $G$ is said to be a {\it suitable set} for $G$ if the identity element $0$ is the unique accumulation point of $S$ and $\langle S\rangle$ is dense in $G$. In this paper, it is proved that every locally compact strongly topological gyrogroup has a suitable set, which gives an affirmative answer to a question posed by F. Lin, et al. in \cite{key14}.
