Star (graph theory)

Summary

In graph theory, the star SkS_{k} is the complete bipartite graph K1, kK_{1,\,k}, that is, it is a tree with one internal node and kk leaves. Alternatively, some authors define SkS_{k} to be the tree of order kk with maximum diameter 2, in which case a star of k>2k > 2 has k−1k - 1 leaves.
