certain kneser graphs, graphs constructed from the intersection patterns of equal-size sets, are locally linear. kneser graphs are described by two parameters, the size of the sets they represent and the size of the universe from which these sets are drawn. the kneser graph k g a, b {\displaystyle kg_{a,b}} has (a b) {...

some graphs that are not themselves locally linear can be used as a framework to construct larger locally linear graphs. one such construction involves line graphs. for any graph g {\displaystyle g}, the line graph l (g) {\displaystyle l(g)} is a graph that has a vertex for every edge of g {\displaystyle g}. two vertic...

the cartesian product of any two locally linear
the cartesian product of any two locally linear graphs remains locally linear, because any triangles in the product come from triangles in one or the other factors. for instance, the nine-vertex paley graph (the graph of the 3-3 duoprism) is the cartesian product of two triangles. the hamming graph h (d, 3) {\displayst...

the question of how many edges locally linear
the question of how many edges locally linear graphs can have is one of the formulations of the ruzsa–szemerédi problem. although dense graphs can have a number of edges proportional to the square of the number of vertices, locally linear graphs have a smaller number of edges, falling short of the square by at least a ...

in graph theory, a locally linear graph is an undirected graph in which every edge belongs to exactly one triangle. equivalently, for each vertex of the graph, its neighbors are each adjacent to exactly one other neighbor, so the neighbors can be paired up into an induced matching. locally linear graphs have also been ...
