Shifting sensibilities? Changes in the symbolism and the appeal of the Crusades after the end of Outremer (Fourteenth century)

open access: yesI Quaderni del MAES, 2022
After 1291, the crusading experience underwent considerable changes, conceptual rather than only military. Despite the loss of the direct experience of the Holy Land, however, the crusading symbolism and institutions did not disappear, but lent ...

Giovanni Bianchi e la tradizione medico-naturalistica partenopea [PDF]

open access: yesLaboratorio dell'ISPF, 2021
From the recovered pieces of a scientific mosaic, scattered by G. Bianchi in the correspondence with A. Catani, it emerges the image of a Neapolitan medical republic and a lively "naturaliter lincea" capital city, heir to the late seventeenth-century ...

Transformation of Bianchi for Minding Top

open access: yesДифференциальная геометрия многообразий фигур, 2021
The work is devoted to the study of the Bianchi transform for surfac­es of revolution of constant negative Gaussian curvature. The surfaces of rotation of constant negative Gaussian curvature are the Minding top, the Minding coil, the pseudosphere ...

Introduction to Hamiltonian formulation of general relativity and homogeneous cosmologies

open access: yesSciPost Physics Lecture Notes, 2023
We give a pedagogical introduction to the Hamiltonian formalism of general relativity at an advanced undergraduate and graduate levels. After covering the mathematical pre-requisites as well as the 3+1-decomposition of spacetime, we proceed to discuss ...

Linearized off-shell 4+7 supergeometry of 11D supergravity

open access: yesJournal of High Energy Physics, 2022
We describe the linearized supergeometry of eleven dimensional supergravity with four off-shell local supersymmetries. We start with a background Minkowski 11D, N=1 superspace, and an additional ingredient of a global, constant, G 2-structure which ...

Bianchi transformation of the pseudosphere

open access: yesДифференциальная геометрия многообразий фигур, 2023
The work is devoted to the study of the Bianchi transform for surfa­ces of constant negative Gaussian curvature. The surfaces of rotation of cons­tant negative Gaussian curvature are the Minding top, the Minding coil, the pseudosphere (Beltrami surface).

Metric algebroid and Dirac generating operator in Double Field Theory

open access: yesJournal of High Energy Physics, 2020
We give a formulation of Double Field Theory (DFT) based on a metric algebroid. We derive a covariant completion of the Bianchi identities, i.e. the pre-Bianchi identity in torsion and an improved generalized curvature, and the pre-Bianchi identity ...

Magnetized Strange Quark Models in Lyra Theory

open access: yesJournal of New Theory, 2023
In this study, the behavior of magnetized strange quark matter (MSQM) distribution in Lyra theory was investigated for homogeneous anisotropic Bianchi III, locally rotationally symmetric (LRS) Bianchi I, and Kantowski-Sachs universe models.

“TRADURRE BISOGNA, NON TRADIRE!”: LE PROPOSTE DI ICILIO BIANCHI IN DIFESA DELLA LINGUA ITALIANA (1939-1940)

open access: yesItaliano LinguaDue, 2022
Il presente articolo si occupa delle proposte di italianizzazione avanzate da Icilio Bianchi sulle pagine della rivista L’albergo in Italia (1939-1940), in mesi immediatamente precedenti all’insediamento della Commissione per l’italianità della lingua ...

Hamiltonian formalism of the Bianchi's models

open access: yesRevista de Investigación de Física, 2022
Lately the Cosmic Background Radiation (CMB) data have resulted in anomalies or deviations with respect to the standard model of cosmology, which has led several cosmologists to consider alternative models to the standard model (homogeneous and isotropic)
