1Quasicrystal — Atomic model of an aluminum palladium manganese (Al Pd Mn) quasicrystal surface. Similar to Fig. 6 in Ref.[1] A quasiperiodic crystal, or, in short, quasicrystal, is a structure that is ordered but not periodic. A quasicrystalline pattern can… …
2quasicrystal — /kway zuy kris tl, kway suy , kwah see , zee /, n. a form of solid matter whose atoms are arranged like those of a crystal but assume patterns that do not exactly repeat themselves. [1985 90] * * * Introduction also called quasi periodic crystal …
3Aperiodic tiling — are an aperiodic set of tiles, since they admit only non periodic tilings of the plane:] Any of the infinitely many tilings by the Penrose tiles is non periodic. More informally, many refer to the Penrose tilings as being aperiodic tilings , but… …
4Kolmogorov–Arnold–Moser theorem — The Kolmogorov–Arnold–Moser theorem is a result in dynamical systems about the persistence of quasi periodic motions under small perturbations. The theorem partly resolves the small divisor problem that arises in the perturbation theory of… …

7Almost Mathieu operator — In mathematical physics, the almost Mathieu operator arises in the study of the quantum Hall effect. It is given by: [H^{lambda,alpha} omega u] (n) = u(n+1) + u(n 1) + 2 lambda cos(2pi (omega + nalpha)) u(n), , acting as a self adjoint operator… …
8Attractor — For other uses, see Attractor (disambiguation). Visual representation of a strange attractor An attractor is a set towards which a dynamical system evolves over time. That is, points that get close enough to the attractor remain close even if… …
9Rothenberg propriety — In music, Rothenberg propriety denotes an important concept in the general theory of scales which was introduced by David Rothenberg in a seminal series of papers in 1978. The concept was independently discovered in a more restricted context by… …
