Random walks on the circle and Diophantine approximation

open access: yesJournal of the London Mathematical Society, Volume 108, Issue 2, Page 409-440, August 2023., 2023
Abstract Random walks on the circle group R/Z$\mathbb {R}/\mathbb {Z}$ whose elementary steps are lattice variables with span α∉Q$\alpha \not\in \mathbb {Q}$ or p/q∈Q$p/q \in \mathbb {Q}$ taken mod Z$\mathbb {Z}$ exhibit delicate behavior. In the rational case, we have a random walk on the finite cyclic subgroup Zq$\mathbb {Z}_q$, and the central limit

Using accounting dataset for agricultural sustainability assessment through a multi‐criteria approach: an Italian case study

open access: yesInternational Transactions in Operational Research, Volume 30, Issue 4, Page 2071-2093, July 2023., 2023
Abstract Sustainability has become a key issue for agricultural systems. In this context, sustainability assessment implies considering different aspects of agricultural activities, including environmental, economic and social issues, and it is usually based on practice‐based indicators.

Fourier‐synthesis approach for static charge‐density reconstruction from theoretical structure factors of CaB6

open access: yesActa Crystallographica Section A, Volume 79, Issue 3, Page 246-272, May 2023., 2023
A novel type of Fourier‐synthesis approach is reported for determining electron‐density distributions and their Laplacians from static structure factors of CaB6. The approach relies on mathematical weighting functions to yield a data set, reproducing all characteristic chemical bonding features of the original quantum‐chemically calculated ...

Evaluation of floral volatile patterns in the genus Narcissus using gas chromatography–coupled ion mobility spectrometry

open access: yesApplications in Plant Sciences, Volume 11, Issue 1, January-February 2023., 2023
Abstract Premise Daffodils (Narcissus, Amaryllidaceae) are iconic ornamentals with a complex floral biology and many fragrant species; however, little is known about floral plant volatile organic compounds (pVOCs) across the genus and additional sampling is desirable.

Making Decisions about How to Solve Nonlinear Dynamical Systems of the Kannan Type in a New Complex Function Space of Formal Power Series

open access: yesJournal of Mathematics, Volume 2023, Issue 1, 2023., 2023
The sufficient settings of the space generated by absolute type‐weighted gamma matrices of rank p in the Nakano complex functions of the formal power series, as well as its associated prequasioperators’ ideal equipped with definite functions, are defined and explained in this paper.

A distributional approach to asymptotics of the Spectral Action [PDF]

open access: yes, 2020
La acción espectral es el concepto natural y apropiado para hablar de una acción en el espacio de triplas espectrales, y fue introducido por primera vez por Chamseddine y Connes en 1997.

Approximation properties of Cesàro means of Vilenkin-Fourier series [PDF]

open access: yes, 2022
This PhD thesis focuses on the investigation of approximation properties of Cesàro means of the Vilenkin-Fourier series. In particular, we obtain some new inequalities related to the rate of Lp approximation by Cesàro means of the Vilenkin-Fourier series
