On the prevalence of elliptic and genus one fibrations among toric hypersurface Calabi-Yau threefolds [PDF]

open access: yesJournal of High Energy Physics, 2019
We systematically analyze the fibration structure of toric hypersurface Calabi-Yau threefolds with large and small Hodge numbers. We show that there are only four such Calabi-Yau threefolds with h 1,1 ≥ 140 or h 2,1 ≥ 140 that do not have manifest ...

Lagrangian Fibrations. [PDF]

open access: yesMilan J Math, 2022
AbstractWe review the theory of Lagrangian fibrations of hyperkähler manifolds as initiated by Matsushita. We also discuss more recent work of Shen–Yin and Harder–Li–Shen–Yin. Occasionally, we give alternative arguments and complement the discussion by additional observations.

Fibration symmetries and cluster synchronization in the Caenorhabditis elegans connectome. [PDF]

open access: yesPLoS ONE
Capturing how the Caenorhabditis elegans connectome structure gives rise to its neuron functionality remains unclear. It is through fiber symmetries found in its neuronal connectivity that synchronization of a group of neurons can be determined.

MIXED SERRE FIBRATION

open access: yesWasit Journal for Pure Sciences, 2022
-In this paper we introduce and study new concept the mixed Serre fibration (M-Serre fibration) on CW-complex space, and Mixed path lifting property (by short M-PLP).

Some Result of Triple Fiber Bundle

open access: yesWasit Journal for Pure Sciences, 2023
The aim of this paper to introduce and and study  new concepts of the Triple fiber bundle, Triple local Serre fibration, Triple path lifting property, and prove that the Triple Hurewicz (Serre)  fiber bundle  over paracompact base space is a Triple ...

Generalized Symmetries in F-theory and the Topology of Elliptic Fibrations

open access: yesSciPost Physics, 2022
We realize higher-form symmetries in F-theory compactifications on non-compact elliptically fibered Calabi-Yau manifolds. Central to this endeavour is the topology of the boundary of the non-compact elliptic fibration, as well as the explicit ...

Indexed Induction and Coinduction, Fibrationally [PDF]

open access: yesLogical Methods in Computer Science, 2013
This paper extends the fibrational approach to induction and coinduction pioneered by Hermida and Jacobs, and developed by the current authors, in two key directions.

P = W for Lagrangian fibrations and degenerations of hyper-Kähler manifolds

open access: yesForum of Mathematics, Sigma, 2021
We identify the perverse filtration of a Lagrangian fibration with the monodromy weight filtration of a maximally unipotent degeneration of compact hyper-Kähler manifolds.
