Introduction to Invariants

A detailed tutorial on invariants and the property of invariance. Step by step tutorial including several examples of invariants for reference.

Invariants are any function or number that displays the property of invariance. Invariance is when a function or number can go through several transformations without changing, or without going outside of its set parameters. The set parameters differ depending on the function or number. Some examples of invariant functions and numbers are the absolute value of a complex number, the degree of a polynomial, and certain parts of a square matrix
