It’s value is 1 for each state in R ℓ, is 0 for each state in the other recurrent classes, and is equal to lim n → ∞ Pr { X n ∈ R ℓ ∣ X 0 = i } for each transient state i (see Exercise 3.13).

WebTrue or False 1. Zero vector can be an eigenvector for a matrix. 2. For a matrix, different eigenvalues can correspond to the same eigenvector. 3. if {u,v,w} is a basis of a vector space, then {u, u+v, u+v+w} is also a basis of the vector space. 4. The null space for a matrix coincides with the null space for its echelon form. 5. WebBv = 0 Given this equation, we know that all possible values of v is the nullspace of B. If v is an eigenvector, we also know that it needs to be non-zero. A non-zero eigenvector therefore means a non-trivial nullspace since v would have to be 0 for a trivial nullspace.
