On Cℵ-Fibrations in Bitopological Semigroups

open access: yesThe Scientific World Journal, 2014
We extend the path lifting property in homotopy theory for topological spaces to bitopological semigroups and we show and prove its role in the Cℵ-fibration property. We give and prove the relationship between the Cℵ-fibration property and an approximate

Type I Almost-Homogeneous Manifolds of Cohomogeneity One—IV

open access: yesAxioms, 2018
This paper is one of a series in which we generalize our earlier results on the equivalence of existence of Calabi extremal metrics to the geodesic stability for any type I compact complex almost homogeneous manifolds of cohomogeneity one. In this paper,

Noncommutative fibrations [PDF]

open access: yesCommunications in Algebra, 2019
We show that faithfully flat smooth extensions are reduced flat, and therefore, fit into the Jacobi-Zariski exact sequence in Hochschild homology and cyclic (co)homology even when the algebras are noncommutative or infinite dimensional. We observe that such extensions correspond to tale maps of affine schemes, and we propose a definition for generic ...

The Transition Function of $G_2$ over $S^6$ [PDF]

open access: yes, 2019
We obtain explicit formulas for the trivialization functions of the ${\rm SU}(3)$ principal bundle $G_2 \to S^6$ over two affine charts. We also calculate the explicit transition function of this fibration over the equator of the six-sphere.

On a Conjecture of Yamaguchi and Yokura

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2020
Let F⟶E⟶pB be a fibration of simply connected elliptic spaces. Our paper investigates the conjecture proposed by T. Yamaguchi and S. Yokura, states that dim Ker π∗pℚ≤ dim Ker H∗p;ℚ+1.

Mirror symmetry for Nahm branes [PDF]

open access: yesÉpijournal de Géométrie Algébrique, 2022
The Dirac--Higgs bundle is a hyperholomorphic bundle over the moduli space of stable Higgs bundles of coprime rank and degree. We provide an algebraic generalization to the case of trivial degree and the rank higher than $1$.

Calibrated fibrations [PDF]

open access: yesCommunications in Analysis and Geometry, 2002
In this paper we investigate the geometry of Calibrated submanifolds and study relations between their moduli-space and geometry of the ambient manifold. In particular for a Calabi-Yau manifold we define Special Lagrangian submanifolds for any Kahler metric on it.

Codensity Lifting of Monads and its Dual [PDF]

open access: yesLogical Methods in Computer Science, 2018
We introduce a method to lift monads on the base category of a fibration to its total category. This method, which we call codensity lifting, is applicable to various fibrations which were not supported by its precursor, categorical TT-lifting.

Twisted D3-brane and M5-brane compactifications from multi-charge spindles

open access: yesJournal of High Energy Physics, 2021
We construct families of supersymmetric AdS3 × Y 7 and AdS3 × Y 8 solutions to type IIB string theory and M-theory, respectively. Here Y 7 is an S 5 fibration over Σ, while Y 8 is an S 4 fibration over Σ g × Σ, where Σ g is a Riemann surface of genus g >

Inductive Data Types Based on Fibrations Theory in Programming

open access: yesJournal of Computing and Information Technology, 2016
Traditional methods including algebra and category theory have some deficiencies in analyzing semantics properties and describing inductive rules of inductive data types, we present a method based on Fibrations theory aiming at those questions above.
