aperiodic function
1Periodic function — Not to be confused with periodic mapping, a mapping whose nth iterate is the identity (see periodic point). In mathematics, a periodic function is a function that repeats its values in regular intervals or periods. The most important examples are …
2Feigenbaum function — In the study of dynamical systems the term Feigenbaum function has been used to describe two different functions introduced by the physicist Mitchell Feigenbaum: * the solution to the Feigenbaum Cvitanović functional equation; and * the scaling… …
3Mathieu function — In mathematics, the Mathieu functions are certain special functions useful for treating a variety of problems in applied mathematics, including vibrating elliptical drumheads, quadrupoles mass filters and quadrupole ion traps for mass… …

5Necklace (combinatorics) — In combinatorics, a k ary necklace of length n is an equivalence class of n character strings over an alphabet of size k, taking all rotations as equivalent. It represents a structure with n circularly connected beads of up to k different colors …
6Markov chain — A simple two state Markov chain. A Markov chain, named for Andrey Markov, is a mathematical system that undergoes transitions from one state to another, between a finite or countable number of possible states. It is a random process characterized …

8Relations between Fourier transforms and Fourier series — In the mathematical field of harmonic analysis, the continuous Fourier transform has very precise relations with Fourier series. It is also closely related to the discrete time Fourier transform (DTFT) and the discrete Fourier transform (DFT).… …
9Perron–Frobenius theorem — In linear algebra, the Perron–Frobenius theorem, proved by Oskar Perron (1907) and Georg Frobenius (1912), asserts that a real square matrix with positive entries has a unique largest real eigenvalue and that the corresponding… …
10Complementary sequences — For complementary sequences in biology, see complementarity (molecular biology). In applied mathematics, complementary sequences (CS) are pairs of sequences with the useful property that their out of phase aperiodic autocorrelation coefficients… …
