Scalar Field Evolution at Background and Perturbation Levels for a Broad Class of Potentials
Fortschritte der Physik, Volume 71, Issue 10-11, November 2023., 2023 Abstract In this paper, a non‐interacting scalar field cosmology with an arbitrary potential using the f‐deviser method that relies on the differentiability properties of the potential is investigated. Using this alternative mathematical approach, a unified dynamical system analysis at a scalar field's background and perturbation levels with arbitrary ...

Resistant memory, notes on some (un-built) monuments for the Italian Resistenza
Festival dell'Architettura Magazine, 2022 The contribution starts from the reflection on the memorial as architectural theme and from the highlighting of the role played by commemorative monuments of the Second World War in the context of post-war reconstruction, then it develops the comparative

A footnote to a theorem of Kawamata
Mathematische Nachrichten, Volume 296, Issue 10, Page 4739-4744, October 2023., 2023 Abstract Kawamata has shown that the quasi‐Albanese map of a quasi‐projective variety with log‐irregularity equal to the dimension and log‐Kodaira dimension 0 is birational. In this note, we show that under these hypotheses the quasi‐Albanese map is proper in codimension 1 as conjectured by Iitaka.

CURVATURE APPROXIMATION FROM PARABOLIC SECTORS
Image Analysis and Stereology, 2017 We propose an invariant three-point curvature approximation for plane curves based on the arc of a parabolic sector, and we analyze how closely this approximation is to the true curvature of the curve.

On certain real hypersurfaces of quaternionic projective space
International Journal of Mathematics and Mathematical Sciences, 1991 We classify certain real hypersurfaces ot a quaternionic projective space satisfying the condition σ(R(X,Y)SZ)=0.

A misura d’uomo. Disegno e proporzione della figura vitruviana
Diségno, 2020 Tra le immagini che descrivono le proporzioni del corpo umano quella di Leonardo da Vinci è sicuramente la più efficace, nonostante l’iconico disegno non segua fedelmente le misure indicate da Vitruvio.

Multiple quantum products in toric varieties
International Journal of Mathematics and Mathematical Sciences, 2002 We generalize the author's formula for Gromov-Witten invariants of symplectic toric manifolds (1999) to those needed to compute the quantum product of more than two classes directly, that is, involving the pullback of the Poincaré dual of the point class
