nonbijektif

Nonbijektif is a term used in mathematics, particularly in the study of functions. It is the opposite of bijektif, which means bijective. A function is said to be nonbijektif if it does not satisfy the conditions of being bijective. These conditions are:

1. Injective (one-to-one): For every element in the codomain, there is at most one element in the domain that maps to it.

2. Surjective (onto): For every element in the codomain, there is at least one element in the domain that maps to it.

If a function fails to meet either of these conditions, it is considered nonbijektif. There are two main types of nonbijektif functions:

1. Non-injective functions: These functions do not satisfy the injective condition. In other words, there exists at least one element in the codomain that is the image of more than one element in the domain.

2. Non-surjective functions: These functions do not satisfy the surjective condition. This means there exists at least one element in the codomain that is not the image of any element in the domain.

Nonbijektif functions are common in various areas of mathematics and have practical applications in fields such as computer science, engineering, and economics. Understanding the properties of nonbijektif functions is crucial for solving problems and developing new theories in these areas.
