| Abstract: | This paper first investigates an interpolation theorem on the number of odd components of co-tree in a connected graph according to the calculation method of Betti deficiency of a graph. Then it gives another interpolation theorem on sub-edge-set＇s deficiency according to the equation of Betti deficiency given by Nebesky and generalizes the already known results. |
