Principle of Mathematical Induction: Also known as
Some sources refer to the Principle of Mathematical Induction as the First Principle of (Mathematical) Induction, to distinguish it from the Second Principle of Mathematical Induction.
Some call it the induction principle.
The abbreviation PMI is often seen.
Some sources call it the Principle of Weak Induction.
Such sources may similarly refer to the Second Principle of Mathematical Induction as the Principle of Strong Induction.
These names are misleading, as both principles are equivalent, and so neither is weaker or stronger than the other.
The process of demonstrating a proof by means of the Principle of Mathematical Induction is often referred to as Proof by (Mathematical) Induction.
