Certain topological properties of the set of Fourier transformable functions with the help of a metric are described. Also determines the proofs of the statements that the set of all Fourier transformable functions is a commutative semi-group with respect to the convolution operation as well as Abelian group with respect to the operation of addition. Metric for two functions belonging to the set of all Fourier transformable functions is defined and the proof that the Fourier transformable functions space is complete with our metric is given. The separability theorem and that the Fourier transformable functions space is disconnected are also discussed.https://jfga.uma.ac.ir/article_2871_ad1a13457890b1c99eeacd2bed49fed4.pdfUniversity of Mohaghegh ArdabiliJournal of Finsler Geometry and its Applications2783-05005120240501Generalized η-Ricci solitons on f -Kenmotsu manifolds admitting a quarter symmetric metric connection8087287810.22098/jfga.2024.14757.1121ENMurat AltunbaşDepartment of Mathematics, Faculty of Arts and Sciences, Erzincan Binali Yıldırım University, Erzincan, TurkeyJournal Article20240227In this paper, we study η-Ricci solitons on 3-dimensional f-Kenmotsu manifolds with respect to a quarter symmetric metric connection.

Rafsanjan, Iran0000-0001-5949-6766Journal Article20240130In this paper, we introduce the notion of T-conformal transformations and T-conformal maps between Riemannian manifolds. Here, T stands for a smooth (1,1)-tensor field defined on the domain of these maps. We start by defining what it means for a map to be T-conformal and also dwell on some basic properties of such type maps. We next specialize our discussion to the situation when the map T satisfies the condition ∇T = 0. Accordingly, we prove Liouville's theorem for T-conformal maps between space forms R<sup>n</sup>(c) as an application under the condition ∇T = 0. The proof relies upon properties of T-conformal maps proved earlier. Broadly, the paper seeks to provide a general understanding of conformal mappings in the presence of a tensor field T and show how classical results such as Liouville's theorem apply.https://jfga.uma.ac.ir/article_2895_228313abfd6514f93e9e5d662378f20d.pdfUniversity of Mohaghegh ArdabiliJournal of Finsler Geometry and its Applications2783-05005120240501On projective Riemann quadratic (PR-quadratic) Finsler metrics115126289610.22098/jfga.2024.14815.1122ENNasrin SadeghzadehDepartment of Mathematics, Faculty of Science, University of Qom, Qom. IranJournal Article20240316This paper focuses on Projective Riemann quadratic (PR-quadratic) Finsler metrics, which are a variant of the Finsler metric in Finsler geometry. The paper introduces a special class of PR-quadratic Finsler metrics, called SPR-quadratic Finsler metrics, which is closed under projective changes with respect to a fixed volume form on M. This class contains the class of Douglas-Weyl metrics and is a subset of the class of Weyl metrics. The paper shows that any SPR-quadratic Finsler metric has a scalar flag curvature and a PR-quadratic Finsler metric has a scalar curvature if and only if it is of SPR-quadratic type. The results presented in this paper contribute to a deeper understanding of the behavior of PR-quadratic Finsler metrics and provide insights into the geometric properties of these metrics.https://jfga.uma.ac.ir/article_2896_3133ebb8c94a17643f2343fc8687925c.pdfUniversity of Mohaghegh ArdabiliJournal of Finsler Geometry and its Applications2783-05005120240501On C3-like Finsler spaces of relatively isotropic mean Landsberg curvature127134293810.22098/jfga.2024.14877.1125ENMaryam MirzazadehDepartment of Mathematics, Faculty of Science, University of Qom, Qom, IranJournal Article20240407In this paper, we study the class of C3-like Finsler metrics with relatively isotropic mean Landsberg.
