Throughout these notes, we let K = R or KC. We use the symbol, for example,
f(x)=r2 to say that the function f is defined by setting f(x)=x for all in the domain.
This is same as writing f(x) 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. 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 M be a von Neumann algebra acting on a separable Hilbert space H, and let P: B(R) → M
be a projection-valued measure affiliated with M.
1. Commutant and Spectral Measures: Prove that if P commutes with every operator in the
commutant M', then P is uniquely determined by its action on M.
2. Measure-Theoretic Decomposition in von Neumann Algebras: Show that H can be
decomposed into a direct integral of Hilbert spaces where P acts as multiplication by
characteristic functions, and relate this decomposition to the structure of M.
3. Spectral Integration within von Neumann Algebras: Demonstrate that for any bounded Borel
function f: R→ C, the operator f(T) defined via the spectral measure P belongs to M,
and that the map ff(T) preserves the von Neumann algebra structure.
Requirements:
Integrate spectral theory with the theory of von Neumann algebras.
•Utilize commutant properties to establish uniqueness of spectral measures.
Apply direct integral decompositions within the context of operator algebras.
