Section 7 Notes: The Lebesgue Integral

Definition 7.1 Let L be the set of real-valued functions f such that for some g and h in (see attached) f=g-h almost everywhere. The set L is called the set of Lebesgue integrable function on and the Lebesgue integral of f is defined as follows: see attached.

Theorem 7.2: If f is Riemann integrable on [a,b], then it is Lebesgue integrable on [a,b] and (see attached)

Theorem 7.3 L is a linear space and the integral is a linear functional on L ; that is, if (see attached) L and (see attached), then (see attached) and (see attached) belong to L and (see attached) and (see attached).
