Shifted Lagrangian thickenings of shifted Poisson derived schemes
We prove that the space of shifted Poisson structures on a derived scheme $X$ locally of finite presentation is equivalent to the space of shifted Lagrangian thickenings out $X$, solving a conjecture in shifted Poisson geometry. As a corollary, we show that for $M$ a compact oriented $d$-dimensional manifold and an $n$-shifted Poisson structure on $X$, the mapping stack $\mathrm{Map}(M,X)$ has an $(n-d)$-shifted Poisson structure. It extends a known theorem for shifted symplectic structures to …

Wess-Zumino-Witten Interactions of Axions: Three-Flavor
We present a complete Lagrangian describing axion interactions with pseudoscalar and (axial-)vector mesons within the three light-flavor quark framework. This formulation incorporates both the standard chiral Lagrangian and the full Wess-Zumino-Witten (WZW) term. By including instanton effects associated with the anomalous $U(1)_A$ symmetry, we demonstrate that physical observables remain invariant under arbitrary chiral phase rotations of the quark fields. This comprehensive Lagrangian provide…

EL-AGHF: Extended Lagrangian Affine Geometric Heat Flow
We propose a constrained Affine Geometric Heat Flow (AGHF) method that evolves so as to suppress the dynamics gaps associated with inadmissible control directions. AGHF provides a unified framework applicable to a wide range of motion planning problems, including both holonomic and non-holonomic systems. However, to generate admissible trajectories, it requires assigning infinite penalties to inadmissible control directions. This design choice, while theoretically valid, often leads to high com…

Elias' Encoding from Lagrangians and Renormalization
An efficient approach to universality and optimality of binary codes for integers known as Elias' encoding can be deduced from the classical constrained optimization and renormalization techniques. The most important properties, such as being a universal prefix code, also follow naturally.

Von der Leyen: Polens neuer Präsident "absolut" an der Seite der Ukraine
EU-Kommissionspräsidentin Ursula von der Leyen hat sich nach der Präsidentschaftswahl in Polen zuversichtlich über das weitere Engagement Warschaus für die Ukraine gezeigt. Die polnische Bevölkerung sei sich in der "Abwehr gegen Russlands imperialistisches Machtstreben" stets einig, sagte von der Leyen am Montagabend in der ZDF…

Brüssel und Berlin hoffen auf gute Zusammenarbeit mit Nawrocki
Im Wahlkampf sorgte Nawrocki mit Aussagen in Brüssel und Berlin für Unruhe. Aus beiden Städten kamen nach dessen Wahlsieg Gratulationen - mit Zwischentönen. Deutlicher wird ein Experte: Polens Präsident werde Europa "neue Kopfschmerzen" bereiten.
