The core principle established is that a change of basis operation in vector spaces can be mathematically formalized using invertible transition matrices constructed from the column vectors of new and old bases. The theory defines the relationship between coordinate representations as $X_B = P^{-1}X$, where $P$ is an invertible matrix formed by placing linearly independent basis vectors as columns, enabling a generalized method for converting coordinates without repeated system-solving procedures. This concept belongs to Linear Algebra within mathematics, specifically addressing vector space transformations and their role in simplifying coordinate computations across different reference frames relative to the parent discipline of applied mathematics and theoretical physics.
