Problem Statement: Let (X,B,) be a σ-finite measure space, and let {T}ex be a family of bounded self-adjoint operators on a Hilbert space K such that T is measurable in the sense that for all k, EK, the map (Tk, l) is measurable. 1. Operator-Valued Integration: Define the operator T = T Τι άμ(π) in the strong operator topology, and prove that T is a bounded self-adjoint operator on K. 2. Spectral Measure Construction: Construct a spectral measure E for T in terms of the spectral measures E of each T, and show that I can be expressed via the spectral theorem using E. 3. Measure-Theoretic Properties of E: Prove that the spectral measure E inherits measurability properties from the family {T} and that the integration process preserves the spectral decomposition. Requirements: • Apply operator-valued integration techniques in Hilbert spaces. Integrate individual spectral measures to form a collective spectral measure. Ensure that measurability conditions are satisfied for the integrated operator.
