Structural induction vs weak induction

WebStrong mathematical induction is only slightly di erent. 2 2 Weak Mathematical Induction 2.1 Introduction Weak mathematical induction is also known as the First Principle of Mathe- … WebMathematical induction can be used to prove that a statement about n is true for all integers n ≥ a. We have to complete three steps. In the base step, verify the statement for n = a. In the inductive hypothesis, assume that the statement holds when n = k for some integer k ≥ a.

As you point out, the difference is minor. In both weak and strong induction, you must prove the base case (usually very easy if not trivial). Then, weak induction assumes that the statement is true for size and you must prove that the statement is true for .
