Laman graph: Sparsity, Rigidity & Planarity

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 {\displaystyle n} vertices such that, for all k ≥ 2 {\displaystyle k\geq 2} , every k {\displaystyle k} -vertex subgraph has at most 2 k − 3 {\displaystyle 2k-3} edges, and such…
