In this paper, we define a notion of an A-bifurcation for a system of differential equations in a separable Hilbert space. By using the methods of the topological degree theory and guiding functions, we prove the theorem on the existence and uniqueness of an A-bifurcation point. It is shown how the abstract result can be applied to study the global structure of the solution set of a feedback control system governed by integro-differential equations
