This means that their is an inner product function that gives the "distance" between two vectors in hilbert space. This same function, when applied to two identical vectors gives the squared "norm" (or length) of that vector which must be positive definite.

Webb3 jan. 2024 · A Hilbert space is an inner product space such that the distance x − y, x − y makes it a complete metric space, i.e. a metric space where sequences are convergent if and only if they are Cauchy. In that sense it is said to be complete. A sequence { x i } i ∈ I in an inner product space ( E, ⋅, ⋅ ) is said to be orthogonal if x i, x j ... Webb§ 1. Random Graphs.
