In this thesis we study an oriented version of perfect path double cover (PPDC). An oriented perfect path double cover (OPPDC) of a graph G is a collection of oriented paths in the symmetric orientation S(G) of G such that each edge of S(G) lies in exactly one of the paths and for each vertex v ∈ V (G) there is a unique path which begins in v (and thus the same holds also for terminal vertices of the paths). First we show that if G has no components which isomorphism to K3 and G is a 3-degenerate graph, then G has an OPPDC. Next we also construct an OPPDC for complete bipartite graph Kn,n and multipartite graph Km(n) (n is odd and m ≠ 3, 5),respectively.
