These groups occur as the Galoisgroups of linear dif f erential and dif f erence equations depending on discrete parameters. Among themain results are three f i niteness theorems, the introduction of numerical invariants such as the limitdegree, a dimension theorem for dif f erence algebraic ...
In this paper we provide some applications of the norm form in some quaternion division algebras over rational field, and we give some properties of Fibonacci sequence and Fibonacci sequence in connection to quaternion elements. We provide some properties of the norm of a rational quaternion algebra...
Abstract Background Social support is widely recognized as a protective factor against psychological distress, especially for the elderly with chronic diseases. Therefore, effective tools for measuring social support are of great significance for both research and clinical practice. This study aims to ...
As reported by Jain and Gupta [5], this class of fluids are characterized by microstructures and rigid, bar-like particles suspended in a viscous medium such as polymeric fluids, liquid crystals, animal blood, suspension solutions, etc. This model couples the field of macro-velocity and micro...
At present she is emeritus professor in the mathematics department of the University of Groningen where she has worked since 1977. Her research interests lie in the area of infinite dimensional systems theory. She is the coauthor of two books in this field: “Infinite Dimensional Systems Theory...
The magnetic field's elimination of degeneracy is notable among them37. Furthermore, it has recently been discovered that when the Aharonov-Bohm (AB) field is introduced to a system, it performs such a function37,38,39,40,41 Interestingly, several research focused on the impacts of this ...
Abstract In this paper, we used the definition of fuzzy vector spaces and fuzzy subsets in combination in order to define fuzzy codes over a fuzzy vector space. We found that the combined definitions did not satisfy the definition of fuzzy vector spaces over a Galois field F2, and gave the...
Then we investigate the basic and hereditary properties of them. Moreover,... Ebrahim Samei - 《Journal of Functional Analysis》 被引量: 39发表: 2006年 Homological properties of piecewise hereditary algebras Let Λ be a finite dimensional algebra over an algebraically closed field k. We will ...
When applying for a PhD or research related jobs, should a LinkedIn profile be a copy of the CV? When learning about algebra and geometry, should I read roughly or try to understand every sentence? How large are the Galilean moons as viewed from Jupiter's surface? ...
We introduce and study a notion of module nuclear dimension for a C * \mathrm{C}^{*} -algebra A which is a C * \mathrm{C}^{*} -module over another C * \mathrm{C}^{*} -algebra 𝔄 {\mathfrak{A}} with compatible actions. We show that the module nuclear di
