For p sufﬁciently small there is a linear transformation A : ker(T ) → 2011-11-07 · dim(ker(A^T)) + dim(im(A^T)) = N. Now remember that dim(im(A^T)) = dim(im(A)) for any matrix A. This is a basic consequence of the fact that the dimension of the image of a matrix is equal to either one of the dimension of its column space, or the dimsnion of its row space. 正如 ker T 表示方程 Tx = 0 线性獨立的解的“个数”， coker T 表示使得方程 Tx = y 有解而必须加于 y 的限制条件的个数。这时秩-零化度定理表述为： index T = dim(V) - dim(W) 可以看到，在这种表述下，我们可以很容易地得到 T 的指标，而不必对 T 作深入研究。 Sejam V e W espaços vetoriais de dimensão finita e T: V → W uma transformação linear. Temos que: dim(V) = dim(ker(T)) + dim(Im(T)) Esse resultado é conhecido But these vectors form a basis for ker(S T) so in particular, a 1 = = a k = 0. Thus fT(y 1);:::;T(y k)gis a linearly independent subset of ker(S) and so dim(ker(S)) k.

Thus, Ker(T) consists exactly of those matrices that commute with A. 2. Let V be a vector space and let T : V !V be linear. Prove that the following statements are However, as rank(T) dim(W), this is clearly false so we conclude that Tcannot be one-to-one.

linear transformation T : V → W is a function from V to W such that ker(T) is a subspace of V and range(T) is a subspace of W. denoted by dim(V). If a vector dim(Rng(T)) = 2. ◁.

Summary: Kernel. 1. we identify T as a linear transformation from Rn to Rm;. 2. find the representation matrix [T] = [T(e1) ··· T(en)];. 4.
