Monotone iterations for differential equations with a parameter
Summary: Consider the problem \(y^\prime(t)=f(t,y(t),\lambda)\), \(t\in J=[0,b]\), \(y(0)=k_0\), \(G(y,\lambda)=0\). Employing the method of upper and lower solutions and the monotone iterative technique, the existence of extremal solutions to the above equation is proved.
