We study the Euler class of co-orientable taut foliations on rational homology spheres. Given a rational homology solid torus $X$, we give necessary and sufficient conditions for the Euler class of taut foliations on Dehn fillings of $X$ that are transverse to the core of the filling solid torus to vanish, from which restrictions on the range of the filling slopes are derived. Precise calculations are done for taut foliations that are carried by certain nice branched surfaces. Implications of…

L-spaces, taut foliations and the Whitehead link

We prove that if M is a rational homology sphere that is a Dehn surgery on the Whitehead link, then M is not an L-space if and only if M supports a coorientable taut foliation. The left orderability

Classical pretzel knots and left orderability

We consider the classical pretzel knots $P(a_1, a_2, a_3)$, where $a_1, a_2, a_3$ are positive odd integers. By using continuous paths of elliptic $\mathrm{SL}_2(\mathbb R)$-representations, we show

Taut foliations, left-orders, and pseudo-Anosov mapping tori

For a large class of 3-manifolds with taut foliations, we construct an action of $\pi_1(M)$ on $\mathbb{R}$ by orientation preserving homeomorphisms which captures the transverse geometry of the

Laminations and groups of homeomorphisms of the circle

Abstract.If M is an atoroidal 3-manifold with a taut foliation, Thurston showed that π1(M) acts on a circle. Here, we show that some other classes of essential laminations also give rise to actions

Monopoles and lens space surgeries

Monopole Floer homology is used to prove that real projective three-space cannot be obtained from Dehn surgery on a nontrivial knot in the three-sphere. To obtain this result, we use a surgery long

Orders

Following Rule 350, Rule 351 sets out the formal minimum requirements to be met by a judicial order outside a decision. These conditions are distinguished by whether the Court, pursuant to the

Integral left-orderable surgeries on genus one fibered knots

Following the classification of genus one fibered knots in lens spaces by Baker, we determine hyperbolic genus one fibered knots in lens spaces on whose all integral Dehn surgeries yield closed

Taut foliations in punctured surface bundles, I

Given a fibred, compact, orientable 3‐manifold with single boundary component, we show that a fibration with fiber surface of negative Euler characteristic can be perturbed to yield taut foliations

In this paper and its continuation [3] we investigate the following question: Let M be a compact oriented irreducible 3-manifold whose boundary is a torus. If TV is obtained by filling dM along an
