Questions and Answers

How does the concept of 'Panitikan' relate to the broader understanding of literature based on the text?

Study Notes

  • The text concerns linear algebra.

Definition of Linear Applications

  • Describes concepts related to linear mappings between vector spaces.

Definition

  • Given two vector spaces E and F over a field K , a mapping f: E -> F is a linear application, if it satisfies two conditions:
    • For all x, y in E, f(x+y) = f(x) + f(y).
    • For all λ in K, for all x in E, f(λx) = λf(x).

Properties

  • If f: E -> F is a linear application:
    • f(0E) = 0F, i.e., f maps the zero vector of E to the zero vector of F.
    • For all x in E, f(-x) = -f(x).
    • For all x1, ..., xn in E, for all λ1, ..., λn in K, f(sum(λixi)) = sum(λif(xi)) for i = 1 to n.

Definition

  • Given two vector spaces E and F over a field K.
  • The set of all linear applications from E to F is denoted as L(E, F).
  • L(E, F) forms a vector space over K.

Definition

  • An endomorphism of a vector space E is a linear application from E to itself.
  • The set of all endomorphisms of E is denoted as L(E).

Definition

  • Given three vector spaces E, F, and G over a field K, and linear applications f in L(E, F) and g in L(F, G).
  • The composition of f by g, denoted as g o f, is defined as:
    • g o f: E -> G, where x is mapped to g(f(x)).
  • g o f is a linear application from E to G, i.e., g o f in L(E, G).

Definition

  • The identity application of E, denoted as IdE, maps every element of E to itself.
    • IdE: E -> E, where x is mapped to x.
  • The identity application IdE is a linear application, i.e., IdE in L(E).

Image and Kernel

  • Discusses the kernel and image of a linear application.

Definition

  • Given a linear application f in L(E, F):
    • The kernel of f, denoted as Ker(f), is the set of all elements in E that are mapped to the zero vector in F.
      • Ker(f) = {x in E | f(x) = 0F}.
    • The image of f, denoted as Im(f), is the set of all elements in F that are the image of some element in E.
    • Im(f) = {y in F | exists x in E, f(x) = y}.
  • Ker(f) is a subspace of E and Im(f) is a subspace of F.

Theorem

  • Given a linear application f in L(E, F):
    • f is injective if and only if Ker(f) = {0E}.
