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

Mathematische Nachrichten, Volume 299, Issue 8, Page 1894-1916, August 2026.
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

Boundary‐Only Weak Deflection by Regular Black Holes, Black‐Bounces, Wormholes, and Static Quadrupolar Spacetimes

Fortschritte der Physik, Volume 74, Issue 8, August 2026.
ABSTRACT We apply the boundary‐only isothermal formulation of finite‐distance weak gravitational deflection to regular black holes, black‐bounces, traversable wormholes, non‐asymptotically flat backgrounds, and static quadrupolar spacetimes. The methodological advance is not a new value for a known bending angle.

Projective Dirac Operators, Twisted K-Theory, and Local Index Formula [PDF]

, 2011
We construct a canonical noncommutative spectral triple for every oriented closed Riemannian manifold, which represents the fundamental class in the twisted K-homology of the manifold.

Frobenius 3-Folds via Singular Flat 3-Webs

Symmetry, Integrability and Geometry: Methods and Applications, 2012
We give a geometric interpretation of weighted homogeneous solutions to the associativity equation in terms of the web theory and construct a massive Frobenius 3-fold germ via a singular 3-web germ satisfying the following conditions: 1) the web germ ...

Investigation of English Language Learners’ Attitudes Toward Global Englishes and Global Englishes Language Teaching in Relation to Their Academic Interests and Experiences With English as a Global Lingua Franca

International Journal of Applied Linguistics, Volume 36, Issue 3, Page 2795-2807, August 2026.
ABSTRACT This study investigates Japanese university students’ attitudes toward Global Englishes (GE) and Global Englishes Language Teaching (GELT), focusing on how these attitudes are shaped by students’ academic interests and experiences using English as a lingua franca (ELF), both abroad and in domestic EFL contexts.

Geometric structures associated with the Chern connection attached to a SODE

Differential Geometry and its Applications, 2013
To each second-order ordinary differential equation $σ$ on a smooth manifold $M$ a $G$-structure $P^σ$ on $J^1(\mathbb{R},M)$ is associated and the Chern connection $\nabla ^σ$ attached to $σ$ is proved to be reducible to $P^σ$; in fact, $P^σ$ coincides generically with the holonomy bundle of $\nabla ^σ$. The cases of unimodular and orthogonal holonomy

Chern connections and Chern curvature of the tangent bundle of almost complex manifolds

, 2004
The $\bar{\partial}_{_{J}}$ operator over an almost complex manifold induces canonical connections of type $(0,1)$ over the bundles of $(p,0)$-forms. If the almost complex structure is integrable then the previous connections induce the canonical holomorphic structures of the bundles of $(p,0)$-forms.

Geometry of product complex Cartan manifolds

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2015
In this paper we consider the product of two complex Cartan manifolds, the outcome being a class of product complex Cartan spaces. Then, we study the relationships between the geometric objects of a product complex Cartan space and its components, (e.g ...

GENERALIZED ABELIAN CHERN-SIMONS THEORIES AND THEIR CONNECTION TO CONFORMAL FIELD THEORIES [PDF]

International Journal of Modern Physics A, 1992
We discuss the generalization of Abelian Chern-Simons theories when θ-angles and magnetic monopoles are included. We map these three dimensional theories into sectors of two-dimensional conformal field theories. The introduction of θ-angles allows us to establish in a consistent fashion a connection between Abelian Chern-Simons and 2-d free scalar ...
