Dear student,

A coincidence point (or simply coincidence) of two mappings is a point in their domain having the same image point under both mappings.

Formally, given two mappings

$f,g \colon X \rightarrow Y$

we say that a point x in X is a coincidence point of f and g if f(x) = g(x).

Coincidence theory (the study of coincidence points) is, in most settings, a generalization of  fixed point theory, the study of points x with f(x) = x. Fixed point theory is the special case obtained from the above by letting X = Y and taking g to be the identity mapping.
