K g is not finitely generated
Let Σg be a closed orientable surface of genus g. The mapping class group Modg of Σg is defined to be the group of isotopy classes of orientationpreserving diffeomorphisms Σg → Σg. Recall that an essential simple closed curve γ in Σg is called a bounding curve, or separating curve, if it is nullhomologous in Σg or, equivalently, if γ separates Σg into two connected components. Let Kg denote the...
متن کاملThe Griffiths Group of a General Calabi-yau Threefold Is Not Finitely Generated
Fn−k+1H 2n−2k+1(X)∼= F n−k+1A2n−2k+1(X)c dFn−k+1A2n−2k(X) . If (Zt )t∈C is a flat family of codimension k algebraic cycles on X parametrized by a smooth irreducible curve C, the map t → kX(Zt − Z0) factors through a homomorphism from the Jacobian J (C) to J 2k−1(X), and one can show that the image of this morphism is a complex subtorus of J 2k−1(X) whose tangent space is contained in Hk−1,k(X) ...
متن کاملThe Kernel of the Magnus Representation of the Automorphism Group of a Free Group Is Not Finitely Generated
In this paper, we show that the abelianization of the kernel of the Magnus representation of the automorphism group of a free group is not finitely generated.
متن کاملThe Modular Group A Finitely Generated Group with Interesting Subgroups
The action of Möbius transformations with real coefficients preserves the hyperbolic metric in the upper half-plane model of the hyperbolic plane. The modular group is an interesting group of hyperbolic isometries generated by two Möbius transformations, namely, an order-two element, g2 HzL = -1 ê z, and an element of infinite order, g• HzL = z + 1. Viewing the action of the group elements on a...
متن کاملAn expansion of the Jones representation of genus 2 and the Torelli group
We study the algebraic property of the representation of the mapping class group of a closed oriented surface of genus 2 constructed by VFR Jones [9]. It arises from the Iwahori–Hecke algebra representations of Artin’s braid group of 6 strings, and is defined over integral Laurent polynomials Z[t, t] . We substitute the parameter t with −e , and then expand the powers e in their Taylor series. ...
