... the authors stated therein that t he solutions of (3.18)and(3.24)areofthesame form because of the positivity of the coefficients on the left-hand side of (3.18)and(3.24). As observed in Remark 3.4 ... (2.31) This completes the proof of the lemma.  Remark 2.4. The above proof uses the convexity of L(x, y;z;X,Y;U,V,S,W)when(x, y; z) is fixed. We already remarked at the beginning of...
