Alternating: In the context of algebra, 'alternating' refers to a specific property of functions or operations, especially in non-associative algebras, where the outcome changes sign when two elements are exchanged. This property plays a critical role in defining certain algebraic structures and their behaviors, particularly in coding theory, where it impacts error detection and correction methods. An alternating function or operation is essential in ensuring that certain algebraic identities hold true and contributes to the overall symmetry and structure within the algebraic framework.
Alternative Algebras: Alternative algebras are a class of non-associative algebras where the associative property holds for products of any two elements when they are multiplied in a certain way. This means that while the general multiplication may not be associative, it still satisfies certain alternative identities. These algebras connect with various structures, including flexible algebras and rings, and have practical applications in areas like coding theory and computer algebra systems.
Anti-commutativity: Anti-commutativity is a property of certain binary operations where swapping the order of the operands results in a change of sign. In mathematical terms, an operation * is anti-commutative if for any elements a and b, it holds that a * b = - (b * a). This concept is important in non-associative algebras as it can lead to unique structures and symmetries relevant in various applications, including coding theory.
Bruck's Theorem: Bruck's Theorem states that in a finite projective plane, any two points are contained in exactly one line, and conversely, any two lines intersect at exactly one point.

The implications of Bruck's Theorem extend to flexible algebras, showcasing the interplay between non-associative operations and projective geometry. Furthermore, it has applications in coding theory, where the properties of non-associative algebras are utilized to design error-correcting codes and combinatorial designs.
Error-correcting codes: Error-correcting codes are mathematical constructs used to detect and correct errors in data transmission or storage. They work by adding redundancy to the original data, allowing the receiver to identify and fix errors that may occur during the process. These codes play a crucial role in ensuring data integrity, particularly in contexts where information is transmitted over unreliable channels or stored in systems prone to errors.
Finite-dimensional algebra: A finite-dimensional algebra is an algebraic structure that consists of a vector space over a field, equipped with an algebra multiplication operation, and has a finite basis. This means that any element of the algebra can be expressed as a linear combination of a finite set of basis elements, making it easier to analyze properties like dimension, structure, and representation. Finite-dimensional algebras are particularly relevant in coding theory as they can be used to construct error-correcting codes and study their properties.

This mathematical framework is particularly relevant in fields like coding theory, where it can enhance error detection and correction techniques.
Jacobi Identity: The Jacobi identity is a fundamental property that applies to certain algebraic structures, particularly in the context of non-associative algebras.
