On Generalized Simple P-injective Rings [PDF]

Al-Rafidain Journal of Computer Sciences and Mathematics, 2005
  In this work, we study generalized simple P-injective rings. New properties of such rings are given, and a characterization of division rings and strongly regular rings in terms of GSP rings is obtained.

The lower bound for number of hexagons in strongly regular graphs with parameters $\lambda=1$ and $\mu=2$ [PDF]

E-Journal of Analysis and Applied Mathematics
The existence of $srg(99,14,1,2)$ has been a question of interest for several decades to the moment. In this paper, we consider the structural properties in general for the family of strongly regular graphs with parameters $\lambda =1$ and $\mu =2$.

SOME RESULTS ON STRONGLY π-REGULAR RIN

Tikrit Journal of Pure Science, 2023
In this paper we study the strongly - regular ring (for short   st. -reg. rg.) and some properties also give some new results of st.  -reg. rg. and its connection with other rings.

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

Journal 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.

On GP- Ideals [PDF]

Al-Rafidain Journal of Computer Sciences and Mathematics, 2009
In this work we give some new properties of GP- ideals as well as the relation between GP- ideals, - π regular and simple ring. Also we consider rings with every principal ideal are GP- ideals and establish relation between such rings with strongly ...

4-REGULAR GRAPH OF DIAMETER 2

Tạp 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.

Maximal Generalization of Pure Ideals [PDF]

Al-Rafidain Journal of Computer Sciences and Mathematics, 2008
The purpose of this paper is to study the class of the rings for which every maximal right ideal is left GP-ideal. Such rings are called MGP-rings and give some of their basic properties as well as the relation between MGP-rings, strongly regular ring ...

Applications of Strongly Regular Cayley Graphs to Codebooks

IEEE 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 ...

Higher Order Hamiltonian Systems with Generalized Legendre Transformation

Mathematics, 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]

Transactions 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.
