Cocyclic Hadamard matrices over Latin rectangles
(Elsevier, 2019)
In the literature, the theory of cocyclic Hadamard matrices has always been developed over finite groups. This paper introduces the natural generalization of this theory to be developed over Latin rectangles. In this ...

Recognition and Analysis of Image Patterns Based on Latin Squares by Means of Computational Algebraic Geometry
(MDPI, 2021-03-21)
With the particular interest of being implemented in cryptography, the recognition and analysis of image patterns based on Latin squares has recently arisen as an efficient new approach for classifying partial Latin squares ...

Mathematical foundations of Santilli isotopies
(Hadronic Press, 2015)
The main objective of this text is to present the most basic and fundamental aspects of the isotopic Lie-Santilli theory, more commonly known as Lie-Santilli isotheory or simply isotheory, for short. To achieve this goal, ...

Gröbner bases and the number of Latin squares related to autotopisms of order ≤7
(Elsevier, 2007)
Latin squares can be seen as multiplication tables of quasigroups, which are, in general, noncommutativeand non-associative algebraic structures. The number of Latin squares having a fixed isotopismin their autotopism group ...

Isotopism and isomorphism classes of certain Lie algebras over finite fields
(Springer, 2015)
In the current paper, we study the distribution into isotopism and isomorphism classes of the relevant family FpnFnp of Lie algebras of basis {e1,…,en}{e1,…,en} and nonzero brackets [ei,en]∈⟨e1,…,en−1⟩[ei,en]∈⟨e1,…,en−1⟩ ...

On the r-dynamic coloring of some fan graph families
(Ovidius University Constanta, 2021)
In this paper, we determine the r-dynamic chromatic number of the fan graph Fm,n and determine sharp bounds of this graph invariant for four related families of graphs: The middle graph M(Fm,n), the total graph T(Fm,n), ...
