William Thurston conjectured over twenty years ago that every compact hyperbolic 3manifold whose boundary is a possibly empty union of tori is finitely covered by a manifold which fibres over the circle. If true, it provides a significant amount of global information about the topology of such manifolds. The first non-trivial examples supporting the conjecture were obtained by Gabai [Ga1] (1986...

We show that \most" Dehn-llings of a non-bered, atoroidal, Haken three-manifold with torus boundary are virtually Haken. 1 Results Suppose that X is a compact, oriented, three-manifold with boundary a torus T: We will pick a basis of H 1 (T) represented by simple loops ; such that = 0 in H 1 (X; Q): We call a longitude and a meridian. A slope, ; on T is the isotopy class of essential unoriented...

Independence preservation, a desirable property in realtime locking protocols that isolates tasks from delays due to unrelated critical sections, is formalized. It is shown that independence preservation is impossible if temporary job migrations are disallowed. The OMIP, a new, asymptotically optimal, independence-preserving locking protocol for clustered scheduling based on migratory priority ...
