Question
Question 2:
Using the file "transformations.xlsx" available at
https://drive.google.com/drive/u/1/folders/1A2B3C4D5E6F7G8H910J, each matrix provided
represents a bounded linear operator on a finite-dimensional vector space.
Instructions:
1. Download the file and review the list of matrices, each labeled with their respective vector space
dimensions.
2. Let T represent a transformation matrix from the file.
Answer the following questions based on T:
a) Prove whether the operator norm of T is bounded, and calculate it for a matrix of your choice.
Describe each step and the principles behind your calculation.
b) Consider a transformation matrix T that represents a compact operator on a Hilbert space.
Demonstrate whether or not I could have an infinite number of non-zero eigenvalues. Use an
example from the dataset and explain how this applies within the concept of compact operators.
c) For a matrix T in the dataset with eigenvalues given in "eigenvalues.txt," calculate the trace of T
and verify if it corresponds to the sum of its eigenvalues. If there is a discrepancy, explain why, based
on the properties of T. Use appropriate theorems and provide a clear, detailed solution.
