Left Invertible Functions
by Open Science Repository Mathematics
A function which has an inverse from the left side is called left invertible. It is obvious that a function is left invertible if and only if it is an injection; that is, if a function is given to be an injection then it has at least one left inverse. The question in this case is that, how many left inverses can be there for a given injective function? This paper will address an independent new approach to derive the formula used to count the number of left inverses of an injection. Keywords:
mathematics, left invertible functions.
