Classification of Some Internal Structures of Degree 120 Related To a Group of Extension𝑂8+ 2 : 2
(IRE Journals, 2023-08-07) Maina, Janet Lilian; Matuya, John Wanyonyi; Njuguna, Edward; Marani, Vincent Nyongesa
This paper uses the modular representation method to classify the internal structures of degree 120 related to a group of extension,𝑶𝟖+ 𝟐 : 2.Specifically, we determine the number of binary linear codes and construct their lattice structure, as well as investigate the properties of some linear codes and designs of minimum weights. Our findings reveal that there are 12 binary linear codes, consisting of 4 doubly even codes, 4 projective codes, 2 irreducible codes, and 2 decomposable codes. We also identify 2 primitive 1-designs of minimum weight. The results demonstrate the potential benefits of using linear codes and designs from finite groups of extension with modular representation methods, such as improved error correction, increased data storage capacity, improved security, efficient designs, and improved computational efficiency. However, it is important to note that this topic can be complex and technical, and we recommend that stakeholders collaborate with experts in the field to ensure the accuracy and reliability of the information being used. Overall, this study contributes to the understanding of the modular representation method and its applications in coding theory and related fields.
Controllability of a quasi-linear heat equation
(Asian Academic Research Associates : AARJMD, 2015-04-01) Andanje, Mulambula; Matuya, John Wanyonyi
In this article we have examined the controllability of the quasi-linear heat equation. We considered distributed controls with support in a small sub-domain. We assumed that the quasi-linear terms are locally Lipschitz. We have proved that there exists a control that drives to desired state within a finite time. Our main objective was to determine the existence, uniquiness and regularity of solutions of controllability of a quasi-linear heat equation
On Skew Quasi-P-Class (Q) Operators
(International Journal of Mathematics And its Applications, 2023-07-07) Wanjala Victor; Matuya, John Wanyonyi; Njuguna, Edward; Marani, Vincent Nyongesa
Skew quasi-p-class (Q) operator is introduced. We show that this class satisfies Bishop’s property. We equally show that this class is isoloid and polaroid. Results linking this class to other classes such as class (Q) are also given and a result showing that this class doesn’t preserve similarity of operators is outlined.
