Clifford Fibrations and Possible Kinematics
Symmetry, Integrability and Geometry: Methods and Applications, 2009 Following Herranz and Santander [Herranz F.J., Santander M., Mem. Real Acad. Cienc. Exact. Fis. Natur. Madrid 32 (1998), 59-84, physics/9702030] we will construct homogeneous spaces based on possible kinematical algebras and groups [Bacry H., Levy ...

The Serre spectral sequence of a noncommutative fibration for de Rham cohomology
, 2005 For differential calculi on noncommutative algebras, we construct a twisted de Rham cohomology using flat connections on modules. This has properties similar, in some respects, to sheaf cohomology on topological spaces.

(Co-)fibration of generalized crossed modules
AIMS MathematicsCrossed modules are algebraic structures that generalize the concept of group extensions. They involve group-like objects (often groups or groupoids) with additional structure and mappings between them that satisfy certain properties. Generalized crossed

The arithmeticity of a Kodaira fibration is determined by its universal cover [PDF]
, 2015 Let $S \to C$ be a Kodaira fibration. Here we show that whether or not the algebraic surface $S$ is defined over a number field depends only on the biholomorphic class of its universal cover.

Resolution of the canonical fiber metrics for a Lefschetz fibration [PDF]
, 2015 We consider the family of constant curvature fiber metrics for a Lefschetz fibration with regular fibers of genus greater than one. A result of Obitsu and Wolpert is refined by showing that on an appropriate resolution of the total space, constructed by ...

A Measurable Stability Theorem for Holomorphic Foliations Transverse to Fibrations
International Journal of Differential Equations, 2012 We prove that a transversely holomorphic foliation, which is transverse to the fibers of a fibration, is a Seifert fibration if the set of compact leaves is not a zero measure subset.

Mirror symmetry and elliptic Calabi-Yau manifolds
Journal of High Energy Physics, 2019 We find that for many Calabi-Yau threefolds with elliptic or genus one fibrations mirror symmetry factorizes between the fiber and the base of the fibration.

Two-variable fibrations, factorisation systems and $\infty $ -categories of spans
Forum of Mathematics, Sigma, 2023 We prove a universal property for $\infty $ -categories of spans in the generality of Barwick’s adequate triples, explicitly describe the cocartesian fibration corresponding to the span functor, and show that the latter restricts to a self ...

Topological invariants and fibration structure of complete intersection Calabi-Yau four-folds [PDF]
, 2014 A bstractWe investigate the mathematical properties of the class of Calabi-Yau four-folds recently found in ref. [1]. This class consists of 921,497 configuration matrices which correspond to manifolds that are described as complete intersections in ...

Wasit Journal for Pure SciencesIn this paper, we introduced concept of fuzzy homotopy lifting property, fuzzy fiber structure is introduced. Also, the definition of the fuzzy lifting function and some theorems in a fuzzy topological space are discussed.
