It also follows that the statements : ' parameter a was held con- stant at a0 \ and c the system was re-defined to include a, which, as a null-function, remained at its initial value of a0 ' are merely two ways of describing the same facts. 21/5. The fact that the field is changed by a change of parameter implies that the stabilities of the lines of behaviour are changed. For instance, consider the system

The fact that the field is changed by a change of parameter implies that the stabilities of the lines of behaviour are changed. For instance, consider the system dx/dt = — x -f ay, dy/dt = x — y -f 1 where x and y have been used for simplicity instead of x± and x2. When a — 0, 1, and 2 respectively, the system has the three fields shown in Figure 21/5 Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Ashby, William Ross.
