Math Problem Statement
Solution
To analyze this problem, we will address the key components step by step based on the provided matrix and the associated details:
Part a) Eigenvalues and Associated Properties
-
Distinct Eigenvalues:
From the text, it appears that the matrix has only one distinct eigenvalue, 0, with multiplicity 1 and eigenspace dimension 1.However, let's verify this by calculating the eigenvalues:
- The eigenvalues are roots of the characteristic polynomial .
- Solving this will confirm whether the eigenvalue is correct and check its algebraic and geometric multiplicities.
-
Multiplicity and Dimensions:
- Algebraic Multiplicity: The number of times appears as a root of the characteristic polynomial. Here, it's given as 1.
- Geometric Multiplicity: The dimension of the eigenspace associated with , which is also stated as 1.
Part b) Diagonalizability of
A matrix is diagonalizable if the algebraic multiplicity of each eigenvalue matches its geometric multiplicity and the sum of geometric multiplicities equals the matrix's size.
- Here, has one eigenvalue, , with:
- Algebraic Multiplicity = 1.
- Geometric Multiplicity = 1.
- Since these match, is diagonalizable.
Conclusion:
The matrix is diagonalizable, as the geometric multiplicities match the algebraic multiplicities for all eigenvalues.
Would you like me to perform explicit calculations for the eigenvalues, eigenspaces, or verify diagonalizability in detail?
Expanding Questions:
- What are the steps to compute the characteristic polynomial of a matrix?
- How do algebraic and geometric multiplicities affect diagonalizability?
- Why is the eigenspace dimension important in determining diagonalizability?
- Could a matrix with only one distinct eigenvalue ever fail to be diagonalizable?
- What are the practical implications of a matrix being diagonalizable?
Tip: To confirm diagonalizability, always compare the sum of eigenspace dimensions to the matrix's size.
