isEndomorphism<T>(morph: ChalkboardMorphism<T, T>): boolean

Checks if a morphism is an endomorphism.

Type Parameters

T

Parameters

morph: ChalkboardMorphism<T, T>
The morphism

Returns boolean

Example

const Z4 = Chalkboard.abal.group(Chalkboard.abal.Z(4), (a, b) => (a + b) % 4, 0, (a) => (4 - a) % 4);
const double = Chalkboard.abal.endomorphism(Z4, (x) => (2 * x) % 4);
const valid = Chalkboard.abal.isEndomorphism(double); // Returns true
