Basis extension

Definition

Basis extension refers to the process of expanding a given basis of a vector space or algebra to include additional vectors while maintaining linear independence. This concept is particularly relevant in Jordan algebras, where one seeks to understand how to extend bases to accommodate new elements and structures while preserving the algebra's properties.
