,Global knot theory in ,, × ℝ,Let .. be a compact oriented surface with or without boundary, and let . be a Morse-Smale vector field on .. which is transverse to the boundary ... (For us, a Morse-Smale vector field is a smooth vector field, having at most isolated non-degenerate singularities, and no limit cycles.) We study oriented knots . in the oriented manifold .. × ℝ.

,Isotopies with restricted cusp crossing for fronts with exactly two cusps of Legendre knots in ,*ℝ,It turns out to be very difficult to generalise our approach for knots in circle bundles. The reason is that we no longer have undercrossings and overcrossings, and hence we do not have arrows, markings, and writhes on the chords.

Simone Bunse,Paul Magnette,Kalypso Nicolaïdisnd of borders, the use of temporary detention centers as part of the toughening of asylum policy, the criminalization of migration, and the marginalization resulting from discrimination against migrants all lead to conflict. This can be explained by the fact that the illegal status afforded migrants
