Isoperimetric and Stable Sets for Log-ConcavePerturbations of Gaussian Measures

open access: yesAnalysis 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

open access: yesComplex 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.

On the Ricci tensor of real hypersurfaces of quaternionic projective space

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1996
We study some conditions on the Ricci tensor of real hypersurfaces of quaternionic projective space obtaining among other results an improvement of the main theorem in [9].

The Invariant Two-Parameter Function of Algebras ψ

open access: yesMathematical and Computational Applications, 2019
At present, the research on invariant functions for algebras is very extended since Hrivnák and Novotný defined in 2007 the invariant functions ψ and φ as a tool to study the Inönü−Wigner contractions (IW ...

The theory of E. Mössel at the root of the plan governing a Gipuzkoan farm house model from the 15th century. Part 1

open access: yesEGA, 2020
Recent research results based on architectural analyses and dendrochronology have enabled the identification of a Gipuzkoan farm house model dating back to the middle of the 15th century. The analysis of several case studies has revealed the existence of

What Does Intarsia Say? Materiality and Spirituality in the Urbino Studiolo☆

open access: yesRenaissance Studies, EarlyView.
Abstract Upon entering the Urbino studiolo of Federico da Montefeltro, the visitor is struck by a material‐charged environment. Surprisingly, only a few scholars have addressed one prominent aspect of the decorative scheme, namely, the feature of intarsia as a medium. Even so, it remains on the sidelines of the discussion.
