An outline of the geometry of space-time with the entire questions and concerns defined with out the necessity for formulation. As such, the writer indicates that this can be certainly geometry, with genuine buildings popular from Euclidean geometry, and which enable certain demonstrations and proofs. The formal arithmetic at the back of those structures is equipped within the appendices.

Xn → x1 · w1 + . . + xn · wn . Now it is easy to verify that the required mapping is the composition f = ϕ ◦ ψ. 42 CHAPTER I. LINEAR VECTOR SPACES AND LINEAR MAPPINGS. Let’s return to initial situation. Suppose that we have a mapping f : V → W that determines a matrix F upon choosing two bases e1 , . . , en and h1 , . . , hm in V and W respectively. The matrix F essentially depends on the choice of bases. In order to describe this dependence we consider four bases — two bases in V and other two bases in W .

Expanding x and y in some basis e1 , . . , en , we get the following formula relating their coordinates: y1 .. y n = F11 .. F1n . . Fn1 x1 .. · .. .. . xn . . 5) of Chapter I. From this formula we derive that x belong to the kernel of the operator f if and only if its coordinates x1 , . . , xn satisfy the homogeneous system of linear equations F11 .. F1n . . Fn1 x1 . .. · ... xn . . Fnn = 0 .. , . 7) 0 The matrix of this system of equations coincides with the matrix of the operator f in the basis e1 , .

So, the choice of bases in V and W defines an isomorphism of Hom(V, W ) and Km×n . , 2004. CHAPTER II LINEAR OPERATORS. § 1. Linear operators. The algebra of endomorphisms End(V ) and the group of automorphisms Aut(V ). A linear mapping f : V → V acting from a linear vector space V to the same vector space V is called a linear operator 1 . Linear operators are special forms of linear mappings. Therefore, we can apply to them all results of previous chapter. However, the less generality the more specific features.
