| Research Abstract |
We published "Introduction to combinatorial algebraic system" (1984) and "Introduction to graph theory(1988)". In these books we considered the enumeration of some relational systems, algebraic systems and graphs.
In this research we continue these studies and have several new results. One of our results will be appeared in the report "Enumeration of digraph with given number of vertices of odd out-degree and vertices of odd in-degree." (accepted by Discrete Mathematics)
