Linear Transform MCQ - 4 - Question 15

Let V and V' be vector spaces over a field F. Then for any t1, t2 ∈ Hom (V, V') 

Detailed Solution for Linear Transform MCQ - 4 - Question 15

A function ρ: V → V' is a linear transformation if it satisfies the following properties for all vectors u and v in V and all scalars λ in the underlying field F:

⇒ ρ(u + v) = ρ(u) + ρ(v) (Preservation of vector addition)
⇒ ρ(λu) = λ ρ(u) (Preservation of scalar multiplication)

Linear Transform MCQ - 4 - Question 16

 then the eigenvalues of A are

Linear Transform MCQ - 4 - Question 17

If A and B are 3 × 3 real matrices such that rank (AB) = 1, then rank (BA) cannot be 

Detailed Solution for Linear Transform MCQ - 4 - Question 17

Here A & B a re 3 × 2 real matrices such that rank (AB) = 1 
So, |AB| = 0 
⇒ |A| |B| = 0 (∴ |AB| = |A| |B|)
⇒ either |A| or |B| should be zero 
So, |BA| = |B||A| = 0 
⇒ BA is singular 
Hence rank (BA) cannot be 3. (Because BA is 3 × 3 matrix)

Linear Transform MCQ - 4 - Question 18

Let T be a linear operator on a finite dimensional vector space V, then which of the following is false

Detailed Solution for Linear Transform MCQ - 4 - Question 18

Explanation:

Let T be a linear operator on a finite-dimensional vector space V, then

(i) Two distinct eigenvectors corresponding to distinct eigenvalues are always linearly independent.

(ii) If λ1 and λ2 are two distinct eigen values of T, then = {0}, where  is eigen space corresponding to λ1.

(iii) T is diagonalizable iff arithmetic multiplicity for each eigenvalues is same as geometric multiplicity.

(iv) T is diagonalizable iff, the minimal polynomial of T is factored in field F.

So from the above properties we can say that (1), (2), (3) are true and (4) is false

Linear Transform MCQ - 4 - Question 19
