Correction terms, Z2-Thurston norm, and triangulations
We show that the correction terms in Heegaard Floer homology give a lower bound to the the genus of one-sided Heegaard splittings and the Z2– Thurston norm. Using a result of Jaco–Rubinstein–Tillmann, this gives a lower bound to the complexity of certain closed 3–manifolds. As an application, we compute the Z2–Thurston norm of the double branched cover of some closed 3–braids, and give upper an...
متن کاملThe Thurston Norm
Suppose a 2-handle is attached to a compact orientable 3-manifold M along an annulus A contained in a subsurface N of a M . If N is compressible in M, but N -A is not, then the Thurston norm is unaffected. This generalizes a series of results due to Przytycki, Jaco, and Johannson. Following Thurston [Th],define the complexity X(S) of an oriented surface S to be -x(C), where C is the union of al...
متن کاملThurston norm revisited
We study noncommutative C∗-algebras arising in geometric topology. Our object are Thurston’s norms on the second homology of Stallings’ fibrations. It is shown that Thurston’s norm is a matter of pure algebra, if one looks at the Bratteli diagram of an AF C∗-algebra attached to measured geodesic laminations on a compact surface of genus greater or equal to 2. This approach leads to computationa...
متن کاملThurston norm and cosmetic surgeries
Two Dehn surgeries on a knot are called cosmetic if they yield homeomorphic manifolds. For a null-homologous knot with certain conditions on the Thurston norm of the ambient manifold, if the knot admits cosmetic surgeries, then the surgery coefficients are equal up to sign.
متن کاملThe Thurston Norm and Harvey
Cochran introduced Alexander polynomials over non–commutative Laurent polynomial rings. Their degrees were studied by Cochran, Harvey and Turaev as they give lower bounds on the Thurston norm. We first extend Cochran’s definition to twisted Alexander polynomials. We then show how Reidemeister torsion relates to these invariants and we give lower bounds on the Thurston norm in terms of the Reide...
