| In this paper, we have two parts to discuss the existence of differentiable solutio-ns of a class of quasilinear iterative equation.The first part mainly by tectonic operator, mainly using Schauder fixed pointtheorem to discuss closed interval in [a, b],quasilinear iterative equations existenceand uniqueness of the solution of the differentiable.The second part,we discuss the existence of the solution of the differentiablewith Schauder-Tychonoff fixed point in the real number. |
