Interactive Illustration 9.3: The function y=x2 is an example of a mapping from the real numbers N=R to the set of real numbers M=R. In linear algebra, the term mapping is traditionally used instead of function, but the meaning is the same, i.e., you start out with an item x,...

Suppose E, F are vector spaces and let φ: E → F be a linear mapping. Then the kernel of φ, denoted by ker φ, is the subset of vectors x ϵ E such that φx = 0. It follows from (1.8) and (1.9) that ker φ is a subspace of E.
Linear Algebra Serge Lang Part of the book series: Undergraduate Texts in Mathematics ((UTM)) 10k Accesses Abstract We shall define the general notion of a mapping, which generalizes the notion of a function. Among mappings, the linear mappings are the most important. A good deal of ...
I proved the theorem that there is unique expansion of R-linear mapping of quaternion algebra relative to the given set of linear and antilinear automorphisms.doi:10.48550/arXiv.1107.1139Kleyn, AleksMathematicsAleks Kleyn, Linear Mappings of Quaternion Algebra, eprint arXiv:1107.1139 (2011)...
In this paper we propose a conseptual framework for the observed properties of discriminants of polylinear forms. The connection with classical problems of linear algebra is shown. A new class of algebraic varieties (hypergrassmanians) is introduced, the particular case of which are grassman ...
(1) A mapping T : Rn-Rm is said to be onto Rm if each b in Rm is the image of at least one x in Rn (满射) (2) A mapping T : Rn-Rm is said to be one-to-one if each b in Rm is the image of at most one x in Rn (单射) §1.9 The Matrix of A Linear ...
