| Abstract: | Two-colored directed graphs with two cycles C1 and C2 are studied. Some necessary and sufficient conditions for this class of special two-colored directed graphs to be primitive are got. And a lower boundary of the primitive exponent of D is given when the number of vertices of C2 is 2. |
