WebApr 22, 2024 · In quantum physics, the state of a system is described by a vector in a Hilbert space (its space of states). When two systems are associated, the space of states of the resulting system is the von Neumann tensor product of the spaces of states of the associated two systems. Simple quantum systems have separable space of states. WebDefinition. A Banach space is a complete normed space (, ‖ ‖). A normed space is a pair (, ‖ ‖) consisting of a vector space over a scalar field (where is commonly or ) together with a distinguished norm ‖ ‖:. Like all norms, this norm induces a translation invariant distance function, called the canonical or induced metric, defined for all vectors , by

Lebesgue spaces are function spaces associated to measure spaces (X, M, μ), where X is a set, M is a σ-algebra of subsets of X, and μ is a countably additive measure on M. Let L (X, μ) be the space of those complex-valued measurable functions on X for which the Lebesgue integral of the square of the absolute value of the function is finite, i.e., for a function f in L (X, μ), The inner product of functions f and g in L (X, μ) is then defined as
