Recall that every closed, oriented, connected 3-manifold M admits a contact form ฮป. We shall give conditions on a periodic orbit P 0 of the Reeb vector field defined by ฮป that allows the construction of an open book decomposition of M \ P 0 into embedded planes asymptotic to P 0 such that P 0 is the

Suppose K(r) is reducible, by Theorem 3 of Gordon and Luecke, K(r) has a lens space as a connected summand. We will show that if the order of the fundamental group of the lens space is r then K(r) is the connected sum of L(r, .) and an irreducible homology 3-sphere. 0 1998 Elsevier Science B.V.

With the help of computer algorithms, we improve the lower bound on the edge Folkman number F e (3, 3; 5) and vertex Folkman number F v (3, 3; 4), and, thus, show that the exact values of these numbers are 15 and 14, respectively. We also present computer enumeration of all critical graphs.
