Mathematical Invariants are properties of class of mathematical objects that don't change under various transformations. Studying invariants are one of the big themes of mathematics. In this video we will see three examples of invariants, one from graph theory called the chromatic number, one from geometry called the Euler Characteristic, and one from Linear Algebra called the Determinant (geometrically and algebraically).
