Summary
1 The Real Number System
1.3 Mathematical Induction
1.3.1 Theorem (Principle of Mathematical Induction)
Precondition
- For each n \in \mathbb{N} let P(n) be a statement about the positive integer n .
- (a) P(n) is true.
- (b) If P(k) is true, P(k+1) is true.
Theorem
If (a) and (b) are true, then P(n) is true for all n \in \mathbb{N}
6 The Riemann and Riemann-Stieltjes Integral
- Cauchy proved the fundamental theorem of calculus.
- “The modern definition of integration was developed by in 1853 by Georg Bernhard Riemann (1826-1866).”
- Lebesgue’s theorem seems important.
- The Riemann-Stieltjes integral arises in many applications in both mathematics and physics.
- The Riemann-Stieltjes integral involves only minor modifications in the definition of the Riemann integral.
