摘要
We show that the diameter of a total domination vertex-critical graph is at most 5(gamma(t) - 1)/3, and that the diameter of an independent domination vertex- critical graph is at most 2(i- 1). For all values of gamma(t) equivalent to 2 (mod 3) there exists a total domination vertex- critical graph with the maximum possible diameter. For all values of i >= 2 there exists an independent domination vertex-critical graph with the maximum possible diameter.
