Applications of the monotone-iterative techniques of V. Lakshmikantham to the solutions of the initial value problem for functional differential equations

In the paper a technique of approximate finding of extremal quasisolutions of an inirial value problem for systems of functional differential equations is justified

Method for solving the periodic problem for integro-differential equations

In the paper a monotone-iterative method for approximate finding a couple of minimal and maximal quasisolutions of the periodic problem for a system of integro-differential equations of Volterra type is justified
