Knot Theory and Manifolds

Prime tangles and composite knots.- An internal hierarchy for 3-manifolds.- The finitely generated intersection property for kleinian groups.- Universal knots.- Involutions and isotopies of lens spaces.- Symmetries of twist-spun knots.- Constructing pseudo-Anosov maps.- Transversality for surfaces in foliated 3-manifolds.- 2-Heights of links.- 3-Manifolds with H2(A,?A)=0 and a conjecture of stallings.- Positive knots have positive Conway polynomials.
