Universal circles for quasigeodesic flows [PDF]

open access: yes, 2006
We show that if M is a hyperbolic 3-manifold which admits a quasigeodesic flow, then pi_1(M) acts faithfully on a universal circle by homeomorphisms, and preserves a pair of invariant laminations of this circle.

The virtual Haken conjecture: Experiments and examples [PDF]

open access: yes, 2002
A 3-manifold is Haken if it contains a topologically essential surface. The Virtual Haken Conjecture says that every irreducible 3-manifold with infinite fundamental group has a finite cover which is Haken.

Dehn filling of the "magic" 3-manifold

open access: yes, 2005
We classify all the non-hyperbolic Dehn fillings of the complement of the chain-link with 3 components, conjectured to be the smallest hyperbolic 3-manifold with 3 cusps. We deduce the classification of all non-hyperbolic Dehn fillings of infinitely many

Hyperbolic Volumes of Two Bridge Cone-Manifolds

open access: yesИзвестия Иркутского государственного университета: Серия "Математика"
In this paper we investigate the existence of hyperbolic, Euclidean and spherical structures on cone-manifolds with underlying space 3-sphere and with singular set a given two-bridge knot.

Ricci solitons on almost Kenmotsu 3-manifolds

open access: yesOpen Mathematics, 2017
Let (M3, g) be an almost Kenmotsu 3-manifold such that the Reeb vector field is an eigenvector field of the Ricci operator. In this paper, we prove that if g represents a Ricci soliton whose potential vector field is orthogonal to the Reeb vector field ...

Far from Perfect: Quantum Error Correction with (Hyperinvariant) Evenbly Codes [PDF]

open access: yesQuantum
We introduce a new class of qubit codes that we call Evenbly codes, building on a previous proposal of hyperinvariant tensor networks. Its tensor network description consists of local, non-perfect tensors describing CSS codes interspersed with Hadamard ...

Length multiplicities of hyperbolic 3-manifolds [PDF]

open access: yesIsrael Journal of Mathematics, 2000
Let $M = H^3/ $ be a hyperbolic 3-manifold, where $ $ is a non-elementary Kleinian group. It is shown that the length spectrum of $M$ is of unbounded multiplicity.

Handle additions producing essential surfaces

open access: yes, 2006
We construct a small, hyperbolic 3-manifold $M$ such that, for any integer $g\geq 2$, there are infinitely many separating slopes $r$ in $\partial M$ so that $M(r)$, the 3-manifold obtained by attaching a 2-handle to $M$ along $r$, is hyperbolic and ...

Developing evidence‐based, cost‐effective P4 cancer medicine for driving innovation in prevention, therapeutics, patient care and reducing healthcare inequalities

open access: yesMolecular Oncology, EarlyView.
The cancer problem is increasing globally with projections up to the year 2050 showing unfavourable outcomes in terms of incidence and cancer‐related deaths. The main challenges are prevention, improved therapeutics resulting in increased cure rates and enhanced health‐related quality of life.
