Problem 15: Spectral Radius and Gelfand's Formula
Problem Statement:
Let A be a bounded linear operator on a Banach space X.
Tasks:
a) Spectral Radius Definition: Define the spectral radius r(4) of the operator A.
b) Gelfand's Formula: State and prove Gelfand's Formula, which relates the spectral radius to the
operator norm:
r(A) = lim ||A" ||¹/"
c) Application to Power Series: Using Gelfand's Formula, determine the radius of convergence of the
power series 4" x for a € X.
d) Visualization: For a finite-dimensional operator represented by a matrix, illustrate the concept of
spectral radius by plotting its eigenvalues in the complex plane and indicating r(A).
