Fortschritte der Physik, Volume 74, Issue 6, June 2026.ABSTRACT We present a clear, step‐by‐step method for counting degrees of freedom and identifying constraints in general field theories. This approach, grounded in the works of Einstein, Hilbert, Cartan, Kuranishi, and, more recently, Seiler, is neither Lagrangian nor Hamiltonian in nature. Instead, it applies directly to the field equations. We offer a

The degree of cooperativism in Europe: Towards an evaluation model for cooperative banking
Annals of Public and Cooperative Economics, Volume 97, Issue 2, Page 247-265, June 2026.Abstract Democracy, social commitment and proximity are fundamental values of cooperative‐based financial institutions. The degree of cooperativism of an entity (or, by extension, of a territorial area or country) can be associated with the intensity with which the entity promotes the inherent values of cooperatives.

Validation of machine learning based scenario generators
Journal of Risk and Insurance, Volume 93, Issue 2, Page 508-533, June 2026.Abstract Machine learning (ML) methods are becoming increasingly important for designing economic scenario generators for internal models. Validating data‐driven models requires different methods than validating classical, theory‐based models. We discuss two novel aspects of such validation: first, checking the multivariate distribution of risk factors,

Lp Radial Blaschke-Minkowski Homomorphisms and Lp Dual Affine Surface Areas
Mathematics, 2019 Schuster introduced the notion of radial Blaschke-Minkowski homomorphism and considered the Busemann-Petty problem for volume forms. Whereafter, Wang, Liu and He presented the L p radial Blaschke-Minkowski homomorphisms and extended Schuster ...

Studies in Applied Mathematics, Volume 156, Issue 6, June 2026.ABSTRACT We study the long‐term dynamics of followers that selectively follow one of multiple leaders on Riemannian manifolds, where the leaders interact through repulsive forces while remaining cohesively bounded. We propose a multileader–follower multiagent system defined on Riemannian manifolds. In our model, each follower chooses exactly one leader

Some inequalities for Lp radial Blaschke-Minkowski homomorphisms1 [PDF]
, 2019 The notion of radial Blaschke-Minkowski homomorphisms was presented by Schuster. Afterwards, Wang et al. introduced Lp radial Blaschke-Minkowski homomorphisms.

Sharp estimates for the Laplacian torsional rigidity with negative Robin boundary conditions
Bulletin of the London Mathematical Society, Volume 58, Issue 6, June 2026.Abstract Motivated by pioneering works of Bandle and Wagner, given a bounded Lipschitz domain Ω⊂Rd$\Omega \subset \mathbb {R}^d$ with d⩾3$d\geqslant 3$, we consider the Robin–Laplacian torsional rigidity τα(Ω)$\tau _\alpha (\Omega)$ with negative boundary parameter α$\alpha$ and we show that sharp inequalities for τα(Ω)$\tau _\alpha (\Omega)$ hold if ...
