WebbThe rank-nullity theorem. by Marco Taboga, PhD. The rank-nullity theorem states that the dimension of the domain of a linear function is equal to the sum of the dimensions of its range (i.e., the set of values in the codomain that the function actually takes) and kernel (i.e., the set of values in the domain that are mapped to the zero vector in the codomain). The rank–nullity theorem is a theorem in linear algebra, which asserts that the dimension of the domain of a linear map is the sum of its rank (the dimension of its image) and its nullity (the dimension of its kernel). Visa mer Here we provide two proofs. The first operates in the general case, using linear maps. The second proof looks at the homogeneous system $${\displaystyle \mathbf {Ax} =\mathbf {0} }$$ for While the theorem … Visa mer 1. ^ Axler (2015) p. 63, §3.22 2. ^ Friedberg, Insel & Spence (2014) p. 70, §2.1, Theorem 2.3 3. ^ Katznelson & Katznelson (2008) p. 52, §2.5.1 4. ^ Valenza (1993) p. 71, §4.3 Visa mer
