f-Fixed Points of Isotone f-Derivations on a Lattice
Discussiones Mathematicae - General Algebra and Applications, 2019 In a recent paper, Çeven and Öztürk have generalized the notion of derivation on a lattice to f-derivation, where f is a given function of that lattice into itself.

Generalized Lorentzian Ricci solitons on 3-dimensional Lie groups associated to the Bott Connection [PDF]
AUT Journal of Mathematics and ComputingIn this paper, we investigate which one of the non-isometric left-invariant Lorentz metrics $g$ on $3$-dimensional Lie groups satisfies the generalized Ricci soliton equation $a{\rm Ric}^B [g] + \dfrac{b}{2}{\cal L}_{ X}^B g +cX^\flat\otimes X^\flat ...

On (r; t; s)-nuclear polynomials
Moroccan Journal of Pure and Applied Analysis, 2022 In this work we extend the concept of (r; t; s)-nuclear operators presented by Lapresté in (Studia math., T. LVII. 1976, 47 – 83) to n-homogeneous polynomials. Factorization and inclusion properties are described.

arXiv, 2023 We re-examine the old question to what extent mathematics may be compared with a game, realizing that a "motley of language games" is the more refined object of comparison. Our analysis owes at least as much to (late) Wittgenstein, updated by a Brandomian emphasis that the rules governing language games be inferential, as to Hilbert, supplemented with ...

Some new results on the prime order Cayley graph of given groups
Acta Universitatis Sapientiae: Mathematica, 2023 In this paper, we study the prime order Cayley graph assigned to the group ℤn for different values of n. We specify some of the graph theoretical properties such as chromatic and perfect matching numbers.

Spectral transition line for the extended Harper's model in the positive Lyapunov exponent regime [PDF]
arXiv, 2017 We study the spectral transition line of the extended Harper's model in the positive Lyapunov exponent regime. We show that both pure point spectrum and purely singular continuous spectrum occur for dense subsets of frequencies on the transition line.

Notes in Pure Mathematics & Mathematical Structures in Physics
, 2023 These Notes deal with various areas of mathematics, and seek reciprocal combinations, explore mutual relations, ranging from abstract objects to problems in physics. * * * Please do not download the book from the arXiv repository: it is an outdated version (I am referring to the latest version in this repository, dating back to March 2023), and the ...

American Journal of Mathematics, Pure and Applied [PDF]
Nature, 1880 THE American Journal of Mathematics was established in 1878 under the auspices of the Johns Hopkins University at Baltimore, and four handsome quarto volumes of 400 pages each have now been published. Prof. Sylvester was editor-in-chief of the first three volumes, being assisted by Mr.
