Nullclines, sometimes called zero-growth isoclines, are encountered in a system of differential equations

Nullcines are the geometric shape for which . In a two-dimensional system, the nullclines can be represented by two lines on a two-dimensional plot. In such a two-dimensional example, the fixed points of the system are located where the lines intersect.
