Math Problem Statement

Define Hilbert space with suitable example.

Solution

A Hilbert space is a complete inner product space—a vector space equipped with an inner product that is also complete with respect to the norm defined by that inner product. This means all Cauchy sequences in the space converge to a limit within the space.

Key Properties of a Hilbert Space:

  1. Inner Product: An operation that assigns a scalar to each pair of vectors, satisfying linearity, symmetry, and positivity. ⟨u,v⟩\langle u, v \rangle defines the "dot product" in generalized terms.

  2. Norm: Derived from
