Fully Reconstructible Graph


A graph G is fully reconstructible in C^d if the graph is determined from its d-dimensional measurement variety. If G is globally rigid in R^d on n>=d+2 vertices, then G is fully reconstructible in C^d (Garamvölgyi et al. 2021). The full reconstructibility problem has been solved for d=1 and d=2 (Bernstein and Gortler 2022).

For G a graph on three or more vertices with no isolated vertices, G is fully reconstructible in C^1 iff it is 3-connected (Garamvölgyi et al. 2021, Bernstein and Gortler 2022).

For G a graph on four or more vertices, G is fully reconstructible in C^2 iff G is generically globally rigid in two dimensions (Garamvölgyi et al. 2021, Bernstein and Gortler 2022).

The disposition of full reconstructibility of graphs in d=3 is not fully determined, although some necessary and some sufficient conditions are known. Bernstein and Gortler (2022) showed that the complete bipartite graph K_(5,5) is fully reconstructible in C^3.
