Abstract
The condition that four complex functions φ1 (z), φ2 (z), ψ1 (z), ψ2 (z̄) are two pairs of mutually conjugate ones \( {{\phi }_{2}}\left( {\bar{z}} \right) = \overline {{{\phi }_{1}}\left( z \right),} {\kern 1pt} {{\psi }_{2}}\left( {\bar{z}} \right) = \overline {{{\psi }_{1}}\left( z \right)} \) to be a real function. This paper presents a necessary and sufficient condition.
