Power law
In
physics, a
power law relationship between two
scalar quantities
x and
y is any such that the relationship can be written as
- y = axk
where
a (the constant of proportionality) and
k (the
exponent of the power law) are constants.
Examples of power law relationships:

Power laws are among the most frequent scaling laws that describe the
scaling invariance found in many natural phenomena.
