چکیده
We show that a compact complex surface which bers smoothly over a curve of genus 2 with bers of genus 2 bers holomorphically. We deduce an improvement of a result in [16], and a characterisation of bered surfaces with zero signature. AMS Classi cation 14H15; 14J29, 20F34, 32L30, 57M50

On actions of discrete groups on nonpositively curved spaces
This note contains several observations concerning discrete groups of non-parabolic isometries of spaces of nonpositive curvature. We prove that (almost all) surface mapping class groups do not admit such actions; in particular, they do not act cocompactly. A new obstruction to the existence of a nonpositively curved metric on closed manifolds is presented. We give examples of 4-manifolds bered...
متن کاملOn regularly fibered complex surfaces
We show that a compact complex surface which fibers smoothly over a curve of genus ≥ 2 with fibers of genus ≥ 2 fibers holomorphically. We deduce an improvement of a result in [16], and a characterisation of fibered surfaces with zero signature. AMS Classification 14H15; 14J29, 20F34, 32L30, 57M50
متن کاملThe Classification of Dehn Surgeries on 2-bridge Knots
We will determine whether a given surgery on a 2-bridge knot is reducible, toroidal, Seifert bered, or hyperbolic. In [Th1] Thurston showed that if K is a hyperbolic knot, then all but nitely many surgeries on K are hyperbolic. In particular, for the Figure 8 knot, it was shown that exactly 9 nontrivial surgeries are non-hyperbolic. Let Kp=q be a 2-bridge knot associated to the rational number ...
متن کاملGauge Structure of Type II K 3
We show that certain classes of K3 bered Calabi-Yau manifolds derive from orbifolds of global products of K3 surfaces and particular types of curves. This observation explains why the gauge groups of the heterotic duals are determined by the structure of a single K3 surface and provides the dual heterotic picture of conifold transitions between K3 brations. Abstracting our construction from the...
متن کاملInvestigation of Effective Parameters of the Two-Layer Sheet Hydroforming Process for Hollow Parts with Complex Geometry
AbstractHydroforming process is a deep stretching process only with the difference that a fluid is used instead of the mandrel. This paper investigates the hydroforming process of non-cylindrical and non-spherical geometries using finite element analysis software to calculate the influences of effective process parameters such as the coefficient of friction between the surfaces and the pressure...
