Could you please clarify for me the relationship between "injective" and "one-to-one" in mathematics? Are they interchangeable terms, or do they refer to slightly different concepts? I'm trying to understand the nuances of these terms in the context of functions and mappings. If they are not the same, could you explain the key differences between them? Additionally, how do these terms apply to functions in cryptography or finance, specifically in the realm of cryptocurrency? Thank you for your assistance in clarifying this matter.

Similarly, surjective and onto describe a property of functions where every element in the codomain is mapped to by at least one element in the domain.

The term bijective combines both injectivity and surjectivity, indicating that a function is both one-to-one and onto. This ensures that there is a one-to-one correspondence between the elements of the domain and the elements of the codomain.

An important aspect of bijective functions is the existence of an inverse. This inverse function reverses the mapping, taking each element in the codomain back to its corresponding element in the domain.

Injectivity and one-to-one mapping are synonymous concepts in mathematics. They refer to a situation where each element in the domain of a function corresponds uniquely to an element in its codomain.
