We use the symbol, for example, f(x)= r² to say that the function f is defined by setting f(x) = r² for all z in the domain. This is same as writing f(x) of 2.

Ilence the emphasis all through had been to look at concrete spaces of function and linear maps between them. This has two advantages: (1) the students get to see the typical applications of the results of functional analysis to other parts of analysis and (2) while dealing with such Problem Statement: Let T be a bounded self-adjoint operator on a separable Hilbert space H, and let V be a bounded self-adjoint perturbation. Consider the perturbed operator T'=T+V. 1. Spectral Measure Perturbation: Prove that the spectral measures ET and ET associated with T and T', respectively, are mutually absolutely continuous if and only if V is compact. 2. Measure-Theoretic Stability of the Spectrum: Analyze how small (in the operator norm) measure-theoretic perturbations V affect the spectrum (T). Prove that under certain conditions on V, the essential spectrum of T remains unchanged. 3. Weyl's Theorem and Measure Theory: Use measure-theoretic concepts to give a proof of Weyl's theorem on the invariance of the essential spectrum under compact perturbations, specifically leveraging the properties of the spectral measures ET and ET. Requirements: • Explore the impact of operator perturbations within the spectral framework. ⚫ Apply measure-theoretic notions of absolute continuity and mutual singularity. ⚫ Utilize classical theorems like Weyl's theorem in a measure-theoretic context.
