We conjecture that every oriented graph G on n vertices with + (G), -(G) β₯ 5n / 12 contains the square of a Hamilton cycle. We also give a conjectural bound on the minimum semidegree which ensures a perfect packing of transitive triangles in an oriented graph. A link between Ramsey numbers and perfe

In this paper we show that any maximal planar graph with m triangles except the unbounded face can be transformed into a straight-line embedding in which at least WmΓ3X triangles are acute triangles. Moreover, we show that any maximal outerplanar graph can be transformed into a straight-line embeddi
The oriented chromatic number o(H) of an oriented graph H is defined to be the minimum order of an oriented graph H' such that H has a homomorphism to H'. If each graph in a class ~ has a homomorphism to the same H', then H' is ~-universal. Let ~k denote the class of orientations of planar graphs wi
