Abstract
The purpose of this paper is to propose a method for studying integrodifferential equations with infinite limits of integration. The main idea of this method is to reduce integrodifferential equations to auxiliary systems of ordinary differential equations.
Results: a scheme of the reduction of integrodifferential equations with infinite limits of integration to these auxiliary systems is described and a formula for representation of bounded solutions, based on fundamental matrices of these systems, is obtained.
Conclusion: methods proposed in this paper could be a basis for the Floquet theory and studies of stability, bifurcations, parametric resonance and various boundary value problems. As examples, models of tumorimmune system interaction, hematopoiesis and planktonnutrient interaction are considered.
