Laman Graph
In graph theory, the Laman graphs are a family of sparse graphs describing the minimally rigid systems of rods and joints in the plane. Formally, a Laman graph is a graph on n vertices such that, for all k\geq 2, every k-vertex subgraph has at most 2k-3 edges, and such that the whole graph has exactly 2n-3 edges. Laman graphs are named after Gerard Laman, of the University of Amsterdam, who in 1970 used them to characterize rigid planar structures. However, this characterization, the Geiringer–Laman theorem, had already been discovered in 1927 by Hilda Geiringer. Rigidity Laman graphs arise in rigidity theory (structural), rigidity theory: if one places the vertices of a Laman graph in the Euclidean plane, in general position, there will in general be no simultaneous continuous motion of all the points, other than Congruence (geometry), Euclidean congruences, that preserves the lengths of all the graph edges. A graph is rigid in this sense if and only if it has a Laman subgraph t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
