Best upper and lower bounds, as functions of n , are obtained for the quantities β 2 (G)+β 2 ( G ̄ ) and α 2 (G)+α 2 ( G ̄ ) , where β 2 ( G ) denotes the total matching number and α 2 ( G ) the total covering number of any graph G with n vertices and with complementry graph Ḡ . The best upper bound is obtained also for α 2 ( G )+ β 2 ( G ), when G is a connected graph. |
