Abstract: Diaz and Walter11]proved a uniqueness theorem for solution of the characteristic boundary value problem uzy=f(x,y,u,ug,u,), u(x,0)=σ(x), 0≤x≤a, u(0,y)=t(y),0≤y≤b, on a rectangle R=[0,a]×[0,b]. We prove an another theorem in this note.The new uniqueness theq- rem is more efficient than the theorem of Diaz-Walter.
