In the theory of dynamical systems, the exponential map can be used as the evolution function of the discrete nonlinear dynamical system.[1]
Family
[edit]The family of exponential functions is called the exponential family.
Forms
[edit]There are many forms of these maps,[2] many of which are equivalent under a coordinate transformation. For example two of the most common ones are:
The second one can be mapped to the first using the fact that , so is the same under the transformation . The only difference is that, due to multi-valued properties of exponentiation, there may be a few select cases that can only be found in one version. Similar arguments can be made for many other formulas.
