Jul 27, 2023 · Definition. The rank rank of a linear transformation L L is the dimension of its image, written. rankL = dim L(V) = dim ranL. (16.21) (16.21) r a n k L = dim L ( V) = dim ran L. The nullity nullity of a linear transformation is the dimension of the kernel, written. nulL = dim ker L. (16.22) (16.22) n u l L = dim ker L. 2 The Adjoint of a Linear Transformation We will now look at the adjoint (in the inner-product sense) for a linear transformation.
