Show that if TEL(V), where V is any finite-dimensional inner product space, and if T is normal, then (a) Im(T) = Im(T*), and (b) null(T) = null(T*).
Problem 6. Let V, W, and U be finite-dimensional vector spaces, and let T : V → W and S : W → U be linear transformations (a) Prove that if B-(Un . . . , v. . . . ,6) is a basis of V such that Bo-(Un .. . ,%) s a basis of ker(T) then (T(Fk+), , T(n)) is a basis of im(T) (b) Prove that if (w!, . . . ,u-, υ, . . . ,i)...
Please give answer with the details. Thanks a lot! Let T: V-W be a linear transformation between vector spaces V and W (1) Prove that if T is injective (one-to-one) and {vi,.. ., vm) is a linearly independent subset of V the n {T(6),…,T(ền)} is a linearly independent subset of W (2) Prove that if the image of any linearly independent subset of V is linearly independent then Tis injective. (3) Suppose that {b1,... bkbk+1,. . . ,b,) is a...

4. Suppose T :V →V is linear. Suppose that R(T) n ker(T) = {Ov}. Let {V1, ..., Vx} be a basis for ker(T) and {W1, ..., Wn} be a basis for R(T). (a) (8 marks) Show that the set {V1, ..., Uk, W1, ..., Wn} is linearly independent. HINT: you might start by assuming that Civi+...+ CkUk + ajwi + ... + anwn = 0 Apply T to both sides of this equation. What can you say about Q1W1+... +...
Problem 4. Suppose V is an n-dimensional complex vector space and TEL(V) is such that dim ker(T"-k) #dim ker(T"-k+1) for some k <n-1. Show that I has at most k eigenvalues. Hint: Is zero an eigenvalue? What is its geometric multiplicity? Solution: Write your solution here.
Problem 3. Let V and W be vector spaces, let T : V -> W be a linear transformation, and suppose U is a subspace of W (a) Recall that the inverse image of U under T is the set T-1 U] := {VE V : T(v) E U). Prove that T-[U] is a subspace of V (b) Show that U nim(T) is a subspace of W, and then without using the Rank-Nullity Theorem, prove that dim(T-1[U]) = dim(Unin (T))...
Let V be a finite-dimensional inner product space. For an operator TEL(V), define its norm by ||T|:= max{||Tull VEV. ||0|| = 1}. (1) To explain this, note that {l|Tu ve V, || 0 || = 1} is a non-empty subset of [0,00). The expression max{||TV|| | V EV, ||0|| = 1} means the maximum, or largest, value in this set. In words, the norm of an operator describes the maximal amount that it 'stretches' (or shrinks) vectors. (a) (1 point)...
