On 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

Commensurability Classes of Twist Knots

In this paper we prove that if MK is the complement of a non-fibered twist knot K in S, then MK is not commensurable to a fibered knot complement in a Z/2Z-homology sphere. To prove this result we derive a recursive description of the character variety of twist knots and then prove that a commensurability criterion developed by D. Calegari and N. Dunfield is satisfied for these varieties. In ad...

Traces, lengths, axes and commensurability

This paper is based on three lectures given by the author at the workshop, “Hyperbolic geometry and arithmetic: a crossview” held at The Université Paul Sabatier, Toulouse in November 2012. The goal of the lectures was to describe recent work on the extent to which various geometric and analytical properties of hyperbolic 3-manifolds determine the commensurability class of such manifolds. This ...

Lagrangian Mechanics and Reduction on Fibered Manifolds

This paper develops a generalized formulation of Lagrangian mechanics on fibered manifolds, together with a reduction theory for symmetries corresponding to Lie groupoid actions. As special cases, this theory includes not only Lagrangian reduction (including reduction by stages) for Lie group actions, but also classical Routh reduction, which we show is naturally posed in this fibered setting. ...

On Hyperbolic 4-manifolds Fibered over Surfaces

In this paper we prove that for any hyperbolic 4-manifold M , which is R 2 bundle over surface , the absolute value of the Euler number e() of the bration : M ! is not greater than exp(exp(10 8 j(()j)). This result partially corroborates a conjecture of Gromov, Lawson and Thurston that je()j j(()j.
