... a passant of P (cf. end of Section 5); 4. all other adjacencies in G, apart from the 5-cycles within each of V 0 , ,V 3 , describe incidences. Proof. It suffices to indicate a proof of the first ... adjacent to X ∈F 2 if and only if v ∈ X. (3) Each coclique in F i ,i {1, 2}, contains 15 vertices of H, and each vertex of H is contained in 15 cocliques of F i . Proof. For...

To complete the proof of the theorem it suffices to show that (for n ≥ 8) replacing 2C 6 by 3C 4 will increase the number of extensions. ... n)be maximising and suppose G(R) consists of c cycles C 2a 1 ,C 2a 2 , ,C 2a c...

... Thus, the conditions of Theorem 3.1 hold, and the initial vector x 0 belongs to S, and hence the solution x(n; x 0 ) of (1.1) and (1.2) is bounded. We consider the scalar case of Volterra difference ... a sufficient, as well as a necessary and sufficient, condition for the boundedness of all solutions of (1.1) and the scalar case of (1.1), respectively. The next...
