Strong Topological Regularity and Weak Regularity of Banach Algebras [PDF]

open access: yesJournal of Sciences, Islamic Republic of Iran, 2011
In this article we study two different generalizations of von Neumann regularity, namely strong topological regularity and weak regularity, in the Banach algebra context.

Applications of Strongly Regular Cayley Graphs to Codebooks

open access: yesIEEE Access, 2023
In this paper, we give a construction of strongly regular Cayley graphs on the finite field $\mathbb {F}_{q^{n}}$ . As applications of these strongly regular Cayley graphs, a class of codebooks is presented and proved to be asymptotically optimal with ...

The Neutrosophic Regular and Most Important Properties that Bind Neutrosophic Ring Elements [PDF]

open access: yesNeutrosophic Sets and Systems, 2023
This research has broadened the definition of the neutrosophic regular in neutrosophic rings, similar to what is known in classical rings. We have studied the properties of neutrosophic regular elements and the most important properties that link them to

Approximately strongly regular graphs

open access: yesDiscrete Mathematics, 2023
We give variants of the Krein bound and the absolute bound for graphs with a spectrum similar to that of a strongly regular graph. In particular, we investigate what we call approximately strongly regular graphs. We apply our results to extremal problems. Among other things, we show the following: (1) Caps in $\mathrm{PG}(n, q)$ for which the number of

4-REGULAR GRAPH OF DIAMETER 2

open access: yesTạp chí Khoa học Đại học Đà Lạt, 2013
A regular graph is a graph where each vertex has the same degree. A regular graph with vertices of degree k is called a k -regular graph or regular graph of degree k.

Higher Order Hamiltonian Systems with Generalized Legendre Transformation

open access: yesMathematics, 2018
The aim of this paper is to report some recent results regarding second order Lagrangians corresponding to 2nd and 3rd order Euler–Lagrange forms. The associated 3rd order Hamiltonian systems are found.

Transitive distance-regular graphs from linear groups $L(3,q)$‎, ‎$q = 2,3,4,5$ [PDF]

open access: yesTransactions on Combinatorics, 2020
In this paper we classify distance-regular graphs‎, ‎including strongly regular graphs‎, ‎admitting a transitive action of the linear groups $L(3,2)$‎, ‎$L(3,3)$‎, ‎$L(3,4)$ and $L(3,5)$ for which the rank of the permutation representation is at most 15‎.

Strongly Semiunits and Tri-Regular Elements in Rings [PDF]

open access: yesEurasian Journal of Science and Engineering, 2018
In this paper we study semiunit elements in the group ring Z2G, where G is a cyclic group and we introduce and discuss strongly semiunit elements in Zn, for n=p, 2p, p2 where p is an odd prime.
