Classification of All Primitive Groups of Degrees Four and Five [PDF]

Eurasian Journal of Science and Engineering, 2017
Let be a compact Riemann surface of genus g and µ:X→𝕡1 be indecomposable meromorphic function of Riemann sphere by . Isomorphisms of such meromorphic functions are in one to one correspondence with conjugacy classes of r tuples(x1 , x2 ,…xr) of ...

On Edge-Primitive Graphs of Order as a Product of Two Distinct Primes

Mathematics, 2023
A graph is edge-primitive if its automorphism group acts primitively on the edge set of the graph. Edge-primitive graphs form an important subclass of symmetric graphs. In this paper, edge-primitive graphs of order as a product of two distinct primes are

1-Designs Constructed from the Groups $PSL_{2}(81)$ and $PSL_{2}(89)$ [PDF]

Journal of Mahani Mathematical Research, 2022
In this paper, some designs from the primitive permutation representations of the groups $PSL_2(81)$ and $PSL_2(89)$ are constructed using the Key-Moori Method 1. We determine the automorphism groups of all the obtained designs and prove that the groups $

PRIMITIVE SUBGROUPS AND PST-GROUPS [PDF]

Bulletin of the Australian Mathematical Society, 2013
AbstractAll groups considered in this paper are finite. A subgroup $H$ of a group $G$ is called a primitive subgroup if it is a proper subgroup in the intersection of all subgroups of $G$ containing $H$ as a proper subgroup.

Comparsion of production performance of two genetic groups of turkeys reared in the Semi-intensive system [PDF]

Journal of Central European Agriculture, 2012
Production results were compared for two groups of turkeys reared in semi-intensive system. The material included 40 primitive turkeys of the light type and 40 heavy hybrids of the Big-6 line (commercial flock).

Cord Blood Plasma and Placental Mesenchymal Stem Cells-Derived Exosomes Increase Ex Vivo Expansion of Human Cord Blood Hematopoietic Stem Cells While Maintaining Their Stemness

Cells, 2023
Background: Mesenchymal stem cells (MSCs) have been used for ex vivo expansion of umbilical cord blood (UCB) hematopoietic stem cells (HSCs) to maintain their primitive characters and long-term reconstitution abilities during transplantation. Therapeutic

The primitive $p$-Frobenius groups [PDF]

Proceedings of the American Mathematical Society, 1998
Let \(p\) be a prime number. A finite primitive permutation group \(G\) acting on a set \(\Omega\) is said to be a primitive \(p\)-Frobenius group iff \(G_{\alpha,\beta}\) is a \(p\)-group for any two distinct \(\alpha,\beta\in\Omega\). In the present paper a complete classification of the primitive \(p\)-Frobenius groups is given (Theorem 1.3).

Primitive permutation IBIS groups [PDF]

Journal of Combinatorial Theory, Series A, 2021
Let $G$ be a finite permutation group on $ $. An ordered sequence of elements of $ $, $( _1,\dots, _t)$, is an irredundant base for $G$ if the pointwise stabilizer $G_{( _1,\dots, _t)}$ is trivial and no point is fixed by the stabilizer of its predecessors. If all irredundant bases of $G$ have the same size we say that $G$ is an IBIS group.
