- Hyperbolic growth
When a quantity grows towards a
singularityunder a finite variation it is said to undergo hyperbolic growth. This growth is created by non-linear positive feedbackmechanisms. Hyperbolic growth is highly nonlinear and it is a stronger form of growth than exponential growth.Fact|date=August 2008
Certain mathematical models suggest that the
world populationundergoes hyperbolic growth. Of course, the same is true for the exponential growth models that also may be valid for certain time periods only.
Another example of hyperbolic growth can be found in
queuing theory: the average waiting time of randomly arriving customers grows hyperbolically as a function of the average load ratio of the server. The singularity in this case occurs when the average amount of work arriving to the server equals the server's processing capacity. If the processing needs exceed the server's capacity, then there is no well-defined average waiting time, as the queue can grow without bound. A practical implication of this particular example is that for highly loaded queuing systems the average waiting time can be extremely sensitive to the processing capacity.
A further practical example of hyperbolic growth can be found in
enzyme kinetics. When the the rate of reaction (termed velocity) between an enzymeand substrate is plotted against various concentrations of the substrate, a hyperbolic plot is obtained for many simpler systems. When this happens, the enzyme is said to follow [http://en.wikipedia.org/wiki/Enzyme_kinetics#Michaelis.E2.80.93Menten_kinetics Michaelis-Menton] kinetics.
