Oscillations of linear integro-differential equations
Sufficient conditions which guarantee that certain linear integro-differential equation cannot have a positive solution are established.
Oscillatory properties of nonlinear differential systems with retarded arguments
Semi-analytical approach to initial problems for systems of nonlinear partial differential equations with constant delay
This paper deals with the differential transform method for solving of an initial value problem for a system of two nonlinear functional partial differential equations of parabolic type. We consider non-delayed as well as delayed types of coupling and the different variety of initial functions are thought over. The convergence of solutions and the error estimation to the presented procedure is studied. Two numerical examples for non-delayed and delayed systems are included.
