Dimension of an eigenspace.
What is an eigenspace of an eigen value of a matrix? (Definition) For a matrix M M having for eigenvalues λi λ i, an eigenspace E E associated with an eigenvalue λi λ i is the set (the basis) of eigenvectors →vi v i → which have the same eigenvalue and the zero vector. That is to say the kernel (or nullspace) of M −Iλi M − I λ i.
The solution given is that, for each each eigenspace, the smallest possible dimension is 1 and the largest is the multiplicity of the eigenvalue (the number of times the root of the characteristic polynomial is repeated).

The algebraic multiplicity is defined to be the highest power of $(t-\lambda)$ that divides the characteristic polynomial.
Or we could say that the eigenspace for the eigenvalue 3 is the null space of this matrix. Which is not this matrix. It's lambda times the identity minus A. So the null space of this matrix is the eigenspace. So all of the values that satisfy this make up the eigenvectors of the eigenspace of lambda is equal to 3.

The geometric multiplicity of is the dimension of the -eigenspace. In other words, dimKer(A Id). The algebraic multiplicity of is the number of times ( t) occurs as a factor of det(A tId). For example, take B = [3 1 0 3]. Then Ker(B 3Id) = Ker[0 1 0 0] is one dimensional, so the geometric multiplicity is 1. But det(B tId) = det 3 t 1 0 3 t
