Abstract

The paper concerns the relationship between the cycles in the graph of a compartmental system and the modes of the impulse response function associated with an input-output experiment. Suppose that there is at least one oscillatory mode, eμtcos(vt - α). Let eρ{variant}t be the slowest mode. The main result is that the system contains a cycle of length 3 or longer and that the length of the longest cycle is at least π/tan-1[|v|/(ρ{variant}-μ)]. The paper also deals with the problem of estimating the cycle length from discrete data.
