5 de mar. de 2021 · Suppose \ (T\in \mathcal {L} (V,V)\) and that \ ( (v_1,\ldots,v_n)\) is a basis of \ (V\). Then the following statements are equivalent: the matrix \ (M (T)\) with respect to the basis \ ( (v_1,\ldots,v_n)\) is upper triangular; \ (Tv_k \in \Span (v_1,\ldots,v_k)\) for each \ (k=1,2,\ldots,n\);
24 de oct. de 2021 · F[x] F [ x] is the vector space of all polynomials of arbitrary degree. Let T: V → V T: V → V and v ∈ V v ∈ V. The order ideal of v v with respect to T T, denoted Ann(T, v) A n n ( T, v) is thet set of all polynomials such that f(T)(v) = 0 f ( T) ( v) = 0.
Definition 9.9.2: Coordinate Vector. Let V be a finite dimensional vector space with dim(V) = n, and let B = {→b1, →b2, …, →bn} be an ordered basis of V (meaning that the order that the vectors are listed is taken into account). The coordinate vector of →v with respect to B is defined as CB(→v).
Suppose \(U,V,W \) are vector spaces over \(\mathbb{F} \) with bases \((u_1,\ldots,u_p) \), \((v_1,\ldots,v_n) \) and \((w_1,\ldots,w_m) \), respectively. Let \(S:U\to V \) and \(T:V\to W \) be linear maps. Then the product is a linear map \(T\circ S:U\to W \). Each linear map has its corresponding matrix \(M(T)=A, M(S)=B \) and \(M(TS)=C \).
8 (a) False: v and w are any vectors in the plane perpendicular to u (b) True: u · (v + 2w) = u · v + 2u · w = 0 (c) True, ku −vk2 = (u −v) · (u −v) splits into u·u+v ·v = 2 when u·v = v ·u = 0. 9 Ifv 2w 2/v 1w 1 = −1thenv 2w 2 = −v 1w 1 orv 1w 1+v 2w 2 = v·w = 0: perpendicular!

26 de dic. de 2022 · If T: V → V and ℬ is a basis of V, the matrix of T with respect to ℬ means [T] ℬ ℬ. Notice that the order of the basis matters in this definition. If you order the basis elements differently, you change the order of the columns or rows in the matrix.
V be a linear operator. [S; T ] := ST T S = 0; then both the range, R[S], and the eigenspaces, E [S] := fv 2 V j Sv = vg. are T -invariant for any 2 F . Indeed, if v 2 R[S], then v = Su for some u 2 V and. T v = T (Su) = (T S)u = (ST )u = S(T u) 2 R[S]: Similarly, if v 2 E [S], then. S(T v) = (ST )v = (T S)v = T (Sv) = T ( v) = v; e., T v is a.
