### Linear Algebra Problem

**Problem Statement:**

Define \( T \in \mathcal{L}(\mathbb{C}^7) \) by
\[ T(z_1, z_2, z_3, z_4, z_5, z_6, z_7) = (z_3, z_4, z_5, z_6, z_7, 0, 0). \]

(a) Prove that there does not exist \( S \in \mathcal{L}(\mathbb{C}^7) \) such that \( S^3 = T \).

(b) Find, with explanation, a Jordan form of \( T \).

**Explanation of the Problem:**

- **Part (a)**: You are required to prove that no linear operator \( S \) on \( \mathbb{C}^7 \) can satisfy the equation \( S^3 = T \). That is, there is no operator \( S \) whose cube is equal to the defined transformation \( T \).

- **Part (b)**: You need to determine the Jordan canonical form of \( T \). The Jordan form is a block diagonal matrix which simplifies the structure of \( T \) and provides insight into its eigenvalues and eigenvectors.

**Steps to Solve the Problem:**

1. **For Part (a)**:
   - Analyze the action of \( T \) by applying it multiple times and observing the outcome.
   - Show that any operator \( S \) which would satisfy \( S^3 = T \) would have to produce the same structure as \( T \) when cubed, which it does not.
  
2. **For Part (b)**:
   - Find the matrix representation of \( T \) if needed.
   - Identify the eigenvalues and eigenvectors of \( T \).
   - Construct the Jordan form by organizing these eigenvalues as blocks along with the generalized eigenvectors.

This problem involves advanced concepts in linear algebra, particularly dealing with linear transformations, eigenvalues, eigenvectors, and Jordan forms.
