Genus one Birkhoff sections for geodesic flows
Pierre Dehornoy
We prove that the geodesic flow on the unit tangent bundle to every hyperbolic 2-orbifold that is a sphere with 3 or 4 singular points admits explicit genus one Birkhoff sections,…
A formula for the Theta invariant from Heegaard diagrams
Christine Lescop
The Theta invariant is the simplest 3-manifold invariant defined with configuration space integrals. It is actually an invariant of rational homology spheres equipped with a combin…
On homotopy invariants of combings of 3-manifolds
Christine Lescop
Combings of oriented compact 3-manifolds are homotopy classes of nowhere zero vector fields in these manifolds. A first known invariant of a combing is its Euler class, that is the…
Local moves for links with common sublinks
Jean-Baptiste Meilhan, Eri Seida, Akira Yasuhara
A C_k-move is a local move that involves (k+1) strands of a link. A C_k-move is called a C_k^d-move if these (k+1) strands belong to mutually distinct components of a link. Since a…
