The purpose of this communication is to announce some slrfficient conditions on degrees and number of arcs to insure the existence of cycles and paths in directed graphs. We show that these results are the best possible. The proofs of the theorems can be found in [4].

The main goal of this work was to describe the basic elements constituting a specialized knowledge base in the field of paths and circuits in digraphs. This knowledge base contains commented on examples with textual and graphical descriptions, invariants, relations among invariants, and theorems. It

In this paper we obtain two sufficient conditions, Ore type (Theorem 1) and Dirac type (Theorem 2). on the degrees of a bipartite oriented graph for ensuring the existence of long paths and cycles. These conditions are shown to be the best possible in a sense. An oriented graph is a digraph without
