We use the symbol, for example, f(x)=2 to say that the function f is defined by setting f(x) = for all z in the domain. This is same as writing f(x) def 2. Can you guess what the symbol 2: f(x) means? LIIS RIIS means that RIIS is defined by LIIS. I started with the principle that a first course in functional analysis is meant first as a part of the general culture and second as an important tool for any future analyst. llence 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 17. Uniformly Convex Spaces and Strong Convergence A Banach space X is uniformly convex if for every € > 0, there exists > 0 such that if || || = ||y|| = 1 and ||xy||≥e, then ||||≤1-8. Prove that every bounded sequence in a uniformly convex Banach space has a unique weak limit, provided it converges weakly. Use this property to show that every weakly convergent sequence in a uniformly convex Banach space converges strongly. ⚫ Hint: Analyze the geometric structure of the unit ball in uniformly convex spaces and apply Clarkson's inequalities if needed. 18. Spectral Properties of Unbounded Operators in Quantum Mechanics Let H = L²(R) and consider the operator T = -on H with domain D(T) = W2,2 (R), the Sobolev space of functions with square-integrable second derivatives. Prove that I is a self-adjoint operator and determine the spectrum of T. Discuss the implications of this result for the quantum harmonic oscillator. Hint: Use Fourier transform techniques to analyze the action of T on L2 (R) and relate it to the spectral properties of T.
