Exponential Map (discrete Dynamical Systems)
In the theory of dynamical systems, the exponential map can be used as the Dynamical system (definition), evolution function of Recurrence relation, the discrete nonlinear dynamical system. Family The family of exponential functions is called the exponential family. Forms There are many forms of these maps,"Bifurcation Loci of Exponential Maps and Quadratic Polynomials: Local Connectivity, Triviality of Fibers, and Density of Hyperbolicity"
Lasse Rempe, Dierk Schleicher many of which are equivalent under a coordinate transformation. For example two of the most common ones are: *E_c : z \to e^z + c *E_\lambda : z \to \lambda * e^z The second one can be mapped to the first using the fact that \lambda * e^z. = e ...

Dynamical System
In mathematics, a dynamical system is a system in which a Function (mathematics), function describes the time dependence of a Point (geometry), point in an ambient space. Examples include the mathematical models that describe the swinging of a clock pendulum, fluid dynamics, the flow of water in a pipe, the Brownian motion, random motion of particles in the air, and population dynamics, the number of fish each springtime in a lake. The most general definition unifies several concepts in mathematics such as ordinary differential equations and ergodic theory by allowing different choices of the space and how time is measured. Time can be measured by integers, by real number, real or complex numbers or can be a more general algebraic object, losing the memory of its physical origin, and the space may be a manifold or simply a Set (mathematics), set, without the need of a Differentiability, smooth space-time structure defined on it. At any given time, a dynamical system has a State ...

At any given time, a dynamical system has a state representing a point in an appropriate state space. This state is often given by a tuple of real numbers or by a vector in a geometrical manifo ...

Recurrence Relation
In mathematics, a recurrence relation is an equation according to which the nth term of a sequence of numbers is equal to some combination of the previous terms. Often, only k previous terms of the sequence appear in the equation, for a parameter k that is independent of n; this number k is called the ''order'' of the relation. If the values of the first k numbers in the sequence have been given, the rest of the sequence can be calculated by repeatedly applying the equation. In ''linear recurrences'', the th term is equated to a linear function of the k previous terms. A famous example is the recurrence for the Fibonacci numbers, F_n=F_+F_ where the order k is two and the linear function merely adds the two previous terms. This example is a linear recurrence with constant coefficients, because the coefficients of the linear function (1 and 1) are constants that do not depend on n. For these recurrences, one can express the general term of the sequence as a closed-form expression o ...

Exponential Function
The exponential function is a mathematical function denoted by f(x)=\exp(x) or e^x (where the argument is written as an exponent). Unless otherwise specified, the term generally refers to the positive-valued function of a real variable, although it can be extended to the complex numbers or generalized to other mathematical objects like matrices or Lie algebras. The exponential function originated from the notion of exponentiation (repeated multiplication), but modern definitions (there are several equivalent characterizations) allow it to be rigorously extended to all real arguments, including irrational numbers. Its ubiquitous occurrence in pure and applied mathematics led mathematician Walter Rudin to opine that the exponential function is "the most important function in mathematics". The exponential function satisfies the exponentiation identity e^ = e^x e^y \text x,y\in\mathbb, which, along with the definition e = \exp(1), shows that e^n=\underbrace_ for positive i ...

Lasse Rempe
Lasse Rempe (born 20 January 1978) is a German mathematician born in Kiel. His research interests include holomorphic dynamics, function theory, continuum theory and computational complexity theory. He currently holds the position of Professor for Pure Mathematics, and Deputy Head of Department for REF at the University of Liverpool. Rempe recorded the voiceover for a BBC feature on the art of mathematics, where he explained how certain pictures have arisen from dynamical systems. Name From 2012 to 2020, he used the name Lasse Rempe-Gillen. Early life and education Rempe earned his Master of Arts degree in mathematics from State University of New York at Stony Brook in 2000 and his doctorate at the University of Kiel in Germany. Awards In June 2010, Rempe was awarded a Whitehead Prize by the London Mathematical Society for his work in complex dynamics, in particular his research on the escaping set for entire functions. In 2012 he was awarded a Philip Leverhulme Prize ...
