Kuga–Satake Construction on Families of K3 Surfaces of Picard Rank 14

open access: yesMathematische Nachrichten, EarlyView.
ABSTRACT The isometry between the type IV6 and the type II4 hermitian symmetric domains suggests a possible relation between suitable moduli spaces of K3 surfaces of Picard rank 14 and of polarized abelian 8‐folds with totally definite quaternion multiplication. We show how this isometry induces a geometrically meaningful map between such moduli spaces

Smarandache rings [PDF]

open access: yes, 2002
Over the past 25 years, I have been immersed in research in Algebra and more particularly in ring theory. I embarked on writing this book on Smarandache rings (Srings) specially to motivate both ring theorists and Smarandache algebraists to develop and ...

SU(3) higher roots and their lattices

open access: yes, 2022
International audienceAfter recalling the notion of higher roots (or hyper-roots) associated with "quantum modules" of type (G, k), for G a semi-simple Lie group and k a positive integer, following the definition given by A. Ocneanu in 2000, we study the

When ${\rm Min}(G)^{-1}$ has a clopen $\pi $-base

open access: yes, 2021
summary:It is our aim to contribute to the flourishing collection of knowledge centered on the space of minimal prime subgroups of a given lattice-ordered group. Specifically, we are interested in the inverse topology.

Acral Melanocytic Lesions Under Conventional, Sub‐Ultraviolet Reflectance, and Ultraviolet‐Induced Fluorescence Dermoscopy: A Comparative Analysis

open access: yesInternational Journal of Dermatology, EarlyView.
Conventional dermoscopy provided higher scores than ultraviolet‐induced fluorescence dermoscopy for parallel furrow pattern, parallel ridge pattern (PRP), fibrillar pattern, dots/clods, radial lines, blue–white structureless areas and blotch, and outperformed sub‐ultraviolet reflectance dermoscopy (sUVRD) for PRP and blue–white structureless areas ...

Invariant Measure and Universality of the 2D Yang–Mills Langevin Dynamic

open access: yesCommunications on Pure and Applied Mathematics, Volume 79, Issue 8, Page 1973-2102, August 2026.
ABSTRACT We prove that the Yang–Mills (YM) measure for the trivial principal bundle over the two‐dimensional torus, with any connected, compact structure group, is invariant for the associated renormalised Langevin dynamic. Our argument relies on a combination of regularity structures, lattice gauge‐fixing and Bourgain's method for invariant measures ...

Normal subgroups in the subgroup lattices of finite $p$-groups

open access: yes, 2006
Given a finite $p$-group $G$ we construct inductively a chief series only by lattice theoretical means. This improves a result of R. Schmidt that shows that any projectivity between finite $p$ groups $G$ and $H$ sends a chief series of $G$ into a chief ...

Hunting Structural Demons in Digital Reticular Chemistry: Lessons From Metal‐Organic Frameworks

open access: yesIsrael Journal of Chemistry, Volume 66, Issue 4, July 2026.
Digital reticular chemistry is haunted by “structural demons”, chemically invalid models lurking within massive experimental and hypothetical MOF databases. This mini‐review tracks where these anomalies enter the data pipeline, evaluate the modern computational arsenal used to detect them (from rule‐based algorithms to machine‐learning classifiers ...

On $\sigma $-permutably embedded subgroups of finite groups

open access: yes, 2019
summary:Let $\sigma =\{\sigma _i\colon i\in I\}$ be some partition of the set of all primes $\mathbb {P}$, $G$ be a finite group and $\sigma (G)=\{\sigma _i\colon \sigma _i\cap \pi (G)\neq \emptyset \}$.
