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 ...

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.

Morse–Radó theory for minimal surfaces
Journal of the London Mathematical Society, Volume 108, Issue 4, Page 1669-1700, October 2023., 2023 Abstract For a class of functions (called minimal Radó functions) that arise naturally in minimal surface theory, we bound the number of interior critical points (counting multiplicity) in terms of the boundary data and the Euler characteristic of the domain of the function.

Applications in Plant Sciences, Volume 11, Issue 5, September-October 2023., 2023 Abstract Premise We recognized the need for a customized imaging protocol for plant specimens at the time of collection for the purpose of three‐dimensional (3D) modeling, as well as the lack of a broadly applicable photogrammetry protocol that encompasses the heterogeneity of plant specimen geometries and the challenges introduced by processes such as

Dynamical Analysis in Chameleon Dark Energy
Fortschritte der Physik, Volume 71, Issue 8-9, September 2023., 2023 Abstract A detailed analysis of the phase‐space for the field equations in scalar field cosmology with a chameleon cosmology in a spatially flat Friedmann–Lemaître–Robertson–Walker spacetime is presented. For the matter source it is assumed that it is an ideal gas with a constant equation of state parameter, while for the scalar field potential and the

The influence of equine hoof conformation on the initiation and progression of laminitis
Equine Veterinary Journal, Volume 55, Issue 5, Page 862-871, September 2023., 2023 Abstract Background The health and performance of horses are significantly affected by diseases associated with the hoof. Laminitis is a critical hoof disease that causes pain and, potentially, severe hoof and bone pathology. Objective To generate an equine hoof finite element (FE) model to investigate the impact of normal and toe‐in hoof conformations

On the structure vector field of a real hypersurface in complex quadric
Open Mathematics, 2018 From the notion of Jacobi type vector fields for a real hypersurface in complex quadric Qm we prove that if the structure vector field is of Jacobi type it is Killing when the real hypersurface is either Hopf or compact.

Isoperimetric and Stable Sets for Log-ConcavePerturbations of Gaussian Measures
Analysis and Geometry in Metric Spaces, 2014 Let be an open half-space or slab in ℝn+1 endowed with a perturbation of the Gaussian measureof the form f (p) := exp(ω(p) − c|p|2), where c > 0 and ω is a smooth concave function depending only onthe signed distance from the linear hyperplane parallel ...

Locally conformal symplectic nilmanifolds with no locally conformal Kähler metrics
Complex Manifolds, 2017 We report on a question, posed by L. Ornea and M. Verbitsky in [32], about examples of compact locally conformal symplectic manifolds without locally conformal Kähler metrics.
