In this study, the existence of a solution of the non-linear singular integral equation system w(z) = f1 z, w(z), h(z), TGg1( · , w( · ), h( · ))(z), ΠGg1( · , w( · ), h( · ))(z) , h(z) = f2 z, w(z), h(z), TGg2( · , w( · ), h( · ))(z), ΠGg2( · , w( · ), h( · ))(z) ,has been investigated. This system is more general than the onew(z) = f1z, w(z), h(z), TGg1( · , w( · ), h( · ))(z) , h(z) = f2 z, w(z), h(z), ΠGg2( · , w( · ), h( · ) (z)), studied by Musayev and Duz (Existence and uniqueness theorems for a certain class of non linear singular integral equations SJAM 10 (1), 3– 18, 2009). Here, TGf(z) and ΠGf(z) are the Vekua integral operators defined by TGf(z) = − 1 π ZZ G f(ς) ς − z dξ dη, ΠGf(z) = − 1 π ZZ G f(ς) (ς − z) 2 dξ d
