Problem Statement:In quantum field theory, observables are often represented by operators in a non-commutativealgebra. Let A be a non-commutative C*-algebra of observables acting on a Hilbert space H, and letbe a state on A.1. Non-Commutative Spectral Measures: Define what constitutes a spectral measure in the non-commutative setting of A, and construct such measures for self-adjoint elements of A.2. Measure-Theoretic States and Spectral Integration: Prove that states induce measure-theoretic structures on the spectral measures of observables, and demonstrate how spectralintegration can be performed with respect to these states.3. Quantum Field Theory Applications: Apply the developed spectral measure framework toanalyze specific observables in quantum field theory, proving results about the distribution ofmeasurement outcomes and the entanglement properties encoded in the spectral measures.Requirements:•Extend spectral measure concepts to non-commutative operator algebras.•Utilize states on C*-algebras to induce measure-theoretic structures.Apply the theory to practical problems in quantum field theory.
