[D.sub.1] and [D.sub.v] are the random diffusion rates of cells and the chemical, respectively; [D.sub.2](u, v)[[nabla].sub.v] represents the chemotactic flux of cells and [D.sub.2](u, v) is positive for positive u and v and is called the sensitivity function; and f(u, v) is the creation rate of the chemical, while k(v)v is the degradation rate of the chemical.
