The Second Variational Formula for Statistical Biharmonic Maps
Recently, the statistical bi-energy functional and its first variational formula were introduced by the author and H. Furuhata. The Maps satisfying the corresponding Euler-Lagrange equation are called statistical biharmonic maps. We present the second variational formula for the statistical bi-energy functional and introduce the notion of stability. If the target statistical manifold is a Hessian manifold, it turns out that the second variational formula can be represented using the Hessian cur…

The Fundamental Theorem of Calculus for Lebesgue-Stieltjes integrals involving non-monotonic derivators
In this work, we extend the concept of the Stieltjes derivative to encompass left-continuous derivators with locally bounded variation, thereby relaxing the monotonicity constraint. This generalization necessitates a refined definition of the Stieltjes derivative applicable across the entire domain, accommodating derivators that may change sign. We establish a generalized Fundamental Theorem of Calculus for the Lebesgue-Stieltjes integral in this broader context, presenting both "almost-everywh…

On strong solution of a multidimensional SDE: extension of Yamada -- Watanabe's theorem
A new strong uniqueness result for a multidimensional SDE with a non-degenerate diffusion and partially irregular drift is established. It may be regarded as a combined variation on the themes of Yamada \& Watanabe (1971), of Zvonkin (1974), and of the second author of the present paper (1980).

M^2VAE: Multi-Modal Multi-View Variational Autoencoder for Cold-start Item Recommendation
Cold-start item recommendation is a significant challenge in recommendation systems, particularly when new items are introduced without any historical interaction data. While existing methods leverage multi-modal content to alleviate the cold-start issue, they often neglect the inherent multi-view structure of modalities, the distinction between shared and modality-specific features. In this paper, we propose Multi-Modal Multi-View Variational AutoEncoder (M^2VAE), a generative model that addre…

Better Call Claude: Can LLMs Detect Changes of Writing Style?
This article explores the zero-shot performance of state-of-the-art large language models (LLMs) on one of the most challenging tasks in authorship analysis: sentence-level style change detection. Benchmarking four LLMs on the official PAN~2024 and 2025 "Multi-Author Writing Style Analysis" datasets, we present several observations. First, state-of-the-art generative models are sensitive to variations in writing style - even at the granular level of individual sentences. Second, their accuracy …

The Enriquez connection for higher genus polylogarithms
We study the variation of the Enriquez connection for higher genus polylogarithms under degenerations of Riemann surfaces with marked points, and show that this connection becomes the connection constructed by the author for degenerating families of pointed Riemann surfaces. Therefore, we have an important application that the higher genus polylogarithms derived from the Enriquez connection can be described explicitly as power series in deformation parameters and their logarithms associated wit…

Portfolio construction using a sampling-based variational quantum scheme
The efficient and effective construction of portfolios that adhere to real-world constraints is a challenging optimization task in finance. We investigate a concrete representation of the problem with a focus on design proposals of an Exchange Traded Fund. We evaluate the sampling-based CVaR Variational Quantum Algorithm (VQA), combined with a local-search post-processing, for solving problem instances that beyond a certain size become classically hard. We also propose a problem formulation tha…

Steve McQueen, Dustin Hoffman - "Papillon" (1973)
Einer der größten, spannendsten und schönsten Filme meines Lebens. Da gibt es gar kein Vertun. Außerdem die einzige Zusammenarbeit von Steve McQueen und Dustin Hoffman. Kein Wunder, dass ich diesen Film lieben musste. Und lesen Sie das Buch! (ARD, Wh)

Ich lese #CarolineWahl ja nicht, aber ich frage mich schon, ob der Feminismus implodiert, wenn das Thema ihres vierten Bestsellers eine Managerin ist, die ihre männlichen Assistenten begrabscht. Entweder, weil sie das nicht selbst erlebt hat (Aneignung) oder weil sie es selbst erlebt hat (Trennung von Werk und Autor). --nach diktat mit fantasie-ferrari verreist
