Definition

C2Linear Algebra

(technical, academic)The simplest polynomial of a matrix that, when applied to the matrix, results in the zero matrix.

Example

  • To find the minimal polynomial of the matrix, we need to determine the lowest-degree polynomial that nullifies it.

C2Field Theory

(technical, academic)The simplest polynomial for which a given algebraic element in an extension field is a root.

Example

  • The minimal polynomial of the element α over the field K is the polynomial of smallest degree with α as a root.
