Boundary Representation — (b rep oder brep) ist eine Darstellungsform eines Flächen oder Volumenmodells, in der Objekte durch ihre begrenzenden Oberflächen beschrieben werden. Der Begriff setzt sich aus den englischen Worten boundary für Begrenzung, Rand und… … Deutsch Wikipedia
Vertex model — A vertex model is a type of statistical mechanics model in which the Boltzmann weights are associated with a vertex in the model (representing an atom or particle). This contrasts with a nearest neighbour model, such as the Ising model, in which… … Wikipedia
Boundary representation — In solid modeling and computer aided design, boundary representation often abbreviated as B rep or BREP is a method for representing shapes using the limits. A solid is represented as a collection of connected surface elements, the boundary… … Wikipedia
Vertex (geometry) — For vertices in the geometry of curves, see Vertex (curve). For other uses of the word, see Vertex (disambiguation). In geometry, a vertex (plural vertices) is a special kind of point that describes the corners or intersections of geometric… … Wikipedia
Top Trees — The Top Tree is a binary tree based data structure for unrooted dynamic trees which is used mainly for carrying out various path related operations, it allows simple Divide and conquer algorithms. It has since been augmented to maintain… … Wikipedia
Van Kampen diagram — In the mathematical area of geometric group theory, a van Kampen diagram is a planar diagram used to represent the fact that a particular word among the generators of a group given by a group presentation represents the identity element in that… … Wikipedia
Orbifold — This terminology should not be blamed on me. It was obtained by a democratic process in my course of 1976 77. An orbifold is something with many folds; unfortunately, the word “manifold” already has a different definition. I tried “foldamani”,… … Wikipedia
Bass–Serre theory — is a part of the mathematical subject of group theory that deals with analyzing the algebraic structure of groups acting by automorphisms on simplicial trees. The theory relates group actions on trees with decomposing groups as iterated… … Wikipedia

Circle packing theorem — Example of the circle packing theorem on K5, the complete graph on five vertices, minus one edge. The circle packing theorem (also known as the Koebe–Andreev–Thurston theorem) describes the possible tangency relations between circles in the plane … Wikipedia
