Bounded operators on Hilbert space

This file connects the abstract operator-algebraic quantum-mechanics API with the concrete C⋆-algebra of bounded operators on a complex Hilbert space. The C⋆-algebra, Loewner order, and ordered-star-ring instances for bounded operators are supplied by Mathlib.

definition

Space of bounded operators B(H)B(H) on a Hilbert space

The notation B(H)B(H) represents the space of bounded (continuous) linear operators from a complex Hilbert space HH to itself, denoted in Lean as `H →L[ℂ] H`.

instance

B(H)\mathcal{B}(\mathcal{H}) is an `OperatorAlgebra`

The space of bounded linear operators B(H)\mathcal{B}(\mathcal{H}) on a complex Hilbert space H\mathcal{H} is equipped with the structure of an `OperatorAlgebra`. This instance links the concrete CC^*-algebra of bounded operators provided by Mathlib to the abstract operator-algebraic API used in quantum mechanics.
