Key Concepts

Change of Inner Product via Basis Transformation

It is possible to define an inner product by selecting a specific basis and assigning inner product values so that the chosen basis becomes orthonormal. This involves using a coordinate transformation or adjusting the metric, leveraging the fact that the inner product is not unique on a vector space.

Gram Matrix

The Gram matrix is formed by taking the inner products of a set of vectors with each other. When the set is orthonormal, the Gram matrix becomes the identity matrix. This concept is useful when constructing or verifying an inner product that gives desired orthogonality and normalization properties to a given basis.

Inner Product

An inner product is a function on a vector space that assigns a scalar to a pair of vectors and satisfies properties of linearity, symmetry (or conjugate symmetry in complex spaces), and positive definiteness. It defines geometric notions such as length and angle in the space.

Orthonormal Basis

An orthonormal basis is a set of vectors in an inner product space that are both orthogonal to each other and of unit length. This means the inner product between any two distinct basis vectors is zero and the inner product of any basis vector with itself is one, making computations in the space particularly simple.
