Let L{\cal L} be a Desarguesian 2-spread in the Grassmann graph Jq(n,2)J_q(n,2). We prove that the collection of the 44-subspaces, which do not contain subspaces from L{\cal L} is a completely regular code in Jq(n,4)J_q(n,4). Similarly, we construct a com... see more

A graph is a mathematical object modeling the existence of a certain relation between pairs of elements of a given set. Many of the first results concerning graphs made reference to relationships between groups of people. In this article, we comment on fo... see more

An ordered regular semigroup, , is said to be principally ordered if for every  there exists . A principally ordered regular semigroup is pointed if for every element,  we have . Here we investigate those principally ordered regular semigroups t... see more

In this paper we define combinatorial structures on the conjugacy classes of the maximal subgroups of the symplectic group S(6,2) under the action of two subgroups of S(6,2) isomorphic to U(3,3) or U(4,2). Further, we examine binary and ternary ... see more

We study binary linear codes constructed from fifty-four Hadamard 2-(71,35,17) designs.The constructed codes are self-dual, doubly-even and self-complementary. Since most of these codeshave large automorphism groups, they are suitable for permutation deco... see more


The article is devoted to the actual scientific problem - the protection of human rights and freedoms by the judicial authorities, their priority in this process. It provides an analysis of international legal acts, devoted to this problem. It is stressed... see more

Fire outbreaks have risen to a worldwide attention in recent years as both an environmental and economic issue. Despite the fact that nothing could be sustainably done to completely stop the occurrence of fire disaster, something could be done to mitigate... see more

This study highlights on the use of code switching in speaking class and its impact toward the students’ language development in target language. Code switching is a regular phenomenon in multilingual conversations. The purposes of the study are to discov... see more
