Spectral properties of substitutions on compact alphabets
Bulletin of the London Mathematical Society, Volume 55, Issue 5, Page 2425-2445, October 2023., 2023 Abstract We consider substitutions on compact alphabets and provide sufficient conditions for the diffraction to be pure point, absolutely continuous and singular continuous. This allows one to construct examples for which the Koopman operator on the associated function space has specific spectral components.

Numerical Methods for Partial Differential Equations, Volume 39, Issue 5, Page 3777-3810, September 2023., 2023 Abstract Recently developed concept of dissipative measure‐valued solution for compressible flows is a suitable tool to describe oscillations and singularities possibly developed in solutions of multidimensional Euler equations. In this paper we study the convergence of the first‐order finite volume method based on the exact Riemann solver for the ...

Counting and boundary limit theorems for representations of Gromov‐hyperbolic groups
Proceedings of the London Mathematical Society, Volume 127, Issue 3, Page 589-652, September 2023., 2023 Abstract Given a Gromov‐hyperbolic group G$G$ endowed with a finite symmetric generating set, we study the statistics of counting measures on the spheres of the associated Cayley graph under linear representations of G$G$. More generally, we obtain a weak law of large numbers for subadditive functions, echoing the classical Fekete lemma.

Random walks on the circle and Diophantine approximation
Journal 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

International 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.

Acta 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 ...

Applications 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.

Journal 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.

Kannan Nonexpansive Operators on Variable Exponent Cesàro Sequence Space of Fuzzy Functions
Journal of Function Spaces, Volume 2022, Issue 1, 2022., 2022 In general, we have constructed the operator ideal generated by extended s‐fuzzy numbers and a certain space of sequences of fuzzy numbers. An investigation into the conditions sufficient for variable exponent Cesàro sequence space of fuzzy functions furnished with the definite function to create pre‐quasi‐Banach and closed is carried out.

Journal of Function Spaces, Volume 2022, Issue 1, 2022., 2022 We have defined and studied the weighted Nakano sequence spaces of fuzzy functions. We have constructed the ideal generated by extended s‐fuzzy functions and the sequence spaces of fuzzy functions. We present some topological and geometric structures of this class of ideal and multiplication mappings acting on this sequence space of fuzzy functions ...
