Finite groups with given nearly S phi-embedded subgroups

期刊: ASIAN-EUROPEAN JOURNAL OF MATHEMATICS, 2021; 14 (08)

Let G be a finite group and H a subgroup of G. Then H is said to be s-permutably embedded in G if a Sylow p-subgroup of H is also a Sylow p-subgroup o......

Lie super-bialgebra structures on the N = 2 super-BMS3 algebra

期刊: ASIAN-EUROPEAN JOURNAL OF MATHEMATICS, 2021; 14 (06)

In this paper, Lie super-bialgebra structures on the N = 2 super-BMS3 algebra are investigated. By computing derivations from the super-BMS3 to the te......

Extremal multiplicative Zagreb indices among trees with given distance k-domination number

期刊: ASIAN-EUROPEAN JOURNAL OF MATHEMATICS, 2021; 14 (05)

The first multiplicative Zagreb index Pi(1) of a graph G is the product of the square of every vertex degree, while the second multiplicative Zagreb i......

Automorphism groups of simply reducible groups

期刊: ASIAN-EUROPEAN JOURNAL OF MATHEMATICS, 2021; 14 (06)

Simply reducible groups are closely related to the eigenvalue problems in quantum theory and molecular symmetry in chemistry. Classification of simply......

Theta series and weight enumerator over an imaginary quadratic field

期刊: ASIAN-EUROPEAN JOURNAL OF MATHEMATICS, 2021; 14 (06)

In this paper, we consider an imaginary quadratic field K = Q(root-m) with - m 3 (mod 4). In particular, we study the ring of integers corresponding t......

On concomitants of dual generalized order statistics from Bairamov-Kotz-Becki Farlie-Gumbel-Morgenstern bivariate distributions

期刊: ASIAN-EUROPEAN JOURNAL OF MATHEMATICS, 2021; 14 (10)

In this paper, we study the concomitants of m-dual generalized order statistics (m-DGOS) from Bairamov-Kotz-Becki Farlie-Gumbel-Morgenstern bivariate ......

On Nagata rings with amalgamation properties

期刊: ASIAN-EUROPEAN JOURNAL OF MATHEMATICS, 2021; 14 (08)

Let R and S be two commutative rings with unity, let J be an ideal of S and phi : R -> S be a ring homomorphism. In this paper, we give a character......

Quasi-automatic semigroups

期刊: ASIAN-EUROPEAN JOURNAL OF MATHEMATICS, 2021; 14 (3)

Quasi-automatic semigroups are extensions of a Cayley graph of an automatic group. Of course, a quasi-automatic semigroup generalizes an automatic sem......

The second-minimum Wiener index of cacti with given cycles

期刊: ASIAN-EUROPEAN JOURNAL OF MATHEMATICS, 2021; 14 (3)

The Wiener index W(G) of a connected graph G is the sum of distances between all pairs of vertices of G. A connected graph G is said to be a cactus if......

Convergence theorems for mixed type iterative process of single-valued and multi-valued nonexpansive mappings and applications

期刊: ASIAN-EUROPEAN JOURNAL OF MATHEMATICS, 2021; 14 (4)

In this paper, we introduce a new mixed type iterative process, which approximates the common fixed points of single-valued nonexpansive mappings and ......

On skew Laplacian spectrum and energy of digraphs

期刊: ASIAN-EUROPEAN JOURNAL OF MATHEMATICS, 2021; 14 (4)

We consider the skew Laplacian matrix of a digraph (G) over right arrow obtained by giving an arbitrary direction to the edges of a graph G having n v......

Some additive results on M-P inverse of operator product

期刊: ASIAN-EUROPEAN JOURNAL OF MATHEMATICS, 2021; 14 (1)

The M-P inverse has many important applications in the aspects of theoretic research of operator and statistics. One of the core problems in M-P inver......
