Final answer:
To use Putzer's method for exponentiating a matrix, determine the eigenvalues and compute their associated eigenprojections, then use these to construct a sequence of matrices, ultimately exponentiating the original matrix based on these projections.
Step-by-step explanation:
The question pertains to Putzer's method for exponentiating a matrix with an eigenvalue of multiplicity three. To find the matrix using Putzer's method, follow these steps:
- Find the eigenvalues of the matrix. Since it is given that there is an eigenvalue of multiplicity three, this eigenvalue is known.
- Compute the associated eigenprojections for the known eigenvalue. Each eigenprojection corresponds to an eigenspace linked to each eigenvalue.
- Use these eigenprojections to construct a sequence of matrices Pi.
- Exponentiate the original matrix according to the recursive relation using these Pi matrices.
To carry out the exponentiation, you might have to use the inverse matrix, apply Euler's formula, find the Jordan normal form, or diagonalize the matrix, depending on the specific matrix you are working with. All entries in the matrices should be integers, as mentioned in the question, and you might use additional computations involving powers and roots as provided in the context of arithmetic examples.
