| Abstract: | In this paper,the class definition and the theory about quasi-paths in a forward mixed hypergraph and an inverse mixed hypergraph are separately discussed in detail. The theory in relation to implication in the forward mixed hypergraph is given, and some theorems in relation to eliminating redundancy in inverse mixed hypergraph are given partially. |

| Keywords: | Mixed hypergraph quasi-path forward inverse. |
