They play a crucial role in understanding the symmetries and internal structures of various algebraic systems. By studying automorphisms, one can gain insights into the underlying symmetry and invariance within structures, revealing deeper connections between elements and operations.
Baric Algebras: Baric algebras are algebraic structures that extend the notion of vector spaces by incorporating an additional scalar multiplication operation. They are particularly useful in various mathematical contexts, including functional analysis and the study of polynomial functions. In baric algebras, elements can be manipulated using both addition and this unique scalar multiplication, which leads to interesting properties and applications in non-associative algebra.
Basis elements: Basis elements are a set of vectors in a vector space that are linearly independent and span the entire space. In various algebraic structures, such as those formed by the Cayley-Dickson construction or gametic algebras, basis elements play a crucial role in defining the dimensionality and the operations within that space. They provide a foundation for constructing every element of the space through linear combinations, thus facilitating analysis and understanding of its structure.
Commutativity: Commutativity is a fundamental property of certain algebraic structures where the order of operations does not affect the result. In mathematical terms, an operation * is commutative if for any elements a and b, the equation a * b = b * a holds true. This property is crucial in various algebraic contexts, influencing the behavior of operations in systems like rings and algebras, including their application in fields such as quantum mechanics and computational methods.
Derivations: Derivations are linear maps that satisfy a product rule, meaning they provide a way to differentiate elements in an algebraic structure while maintaining the algebra's operations.

It's a crucial tool for understanding how multiplication works and helps in visualizing the relationships between numbers. In the context of gametic algebras, multiplication tables are used to define binary operations systematically, enabling the exploration of algebraic structures and their properties.
Non-associativity: Non-associativity refers to a property of certain algebraic structures where the grouping of elements in an operation affects the outcome. This means that for some operations, changing the way in which elements are grouped can lead to different results, which is a key feature in alternative rings and other algebraic systems. Non-associativity has important implications in various mathematical constructs, particularly in those involving higher-dimensional numbers and certain types of algebras that do not follow traditional associative laws.
