Gelfand Theory for Commutative Banach Algebras Prove the Gelfand representation theorem, which states that if A is a commutative Banach algebra with unit, then each element a Є A can be represented as a continuous function on the maximal ideal space M(A) of A. Use this theorem to analyze the spectrum of elements in A and show how it provides insight into spectral theory. Application of Hahn-Banach Theorem in Spectral Theory Use the Hahn-Banach theorem to prove that if T is a bounded linear operator on a Banach space X, and if is not in the spectrum of T, then the operator T - AI has a bounded inverse. Then, discuss the implications of this result in identifying the spectrum and provide examples of how it is applied in practice.
