In the present article we discuss necessary and sufficient conditions for concave functions, i.e. meromorphic functions which map the unit disk conformally on a domain whose complement is convex. The conditions will be given with respect to an arbitrary point p ∈ (-1, 1). We will also look at representation formulas for the related functions as well as an application of the derived formula.
