Hyperbolic 3-manifolds whose fundamental groups are subgroups of finite index in right-
angled Coxeter groups are under consideration. The construction of such manifolds is …

Как известно [1; гл. 1, § 2], в 1890 г. Ф. Клейн, вдохновленный некоторыми примерами

The notion of a layered triangulation of a lens space was defined by Jaco and Rubinstein,
and unless the lens space is L (3, 1), a layered triangulation with the minimal number of …

We collect and discuss various results on an important family of knots and links called Turk's
head knots and links $ Th (p, q) $. In the mathematical literature, they also appear under …

Let $ M $ be a compact 3--manifold with boundary a single torus. We present upper and
lower complexity bounds for closed 3--manifolds obtained as even Dehn fillings of $ M. $ As …

We consider closed orientable 3-dimensional hyperbolic manifolds which are cyclic
branched coverings of the 3-sphere, with branching set being a two-bridge knot (or link). We …

The triangulation complexity of a closed orientable 3-manifold is the minimal number of
tetrahedra in any triangulation of the manifold. The main theorem of the paper gives upper …

Using deep analytic methods, Cheeger and Gromov showed that for any smooth (4k‐1)‐
manifold there is a universal bound for the von Neumann L2 ρ‐invariants associated to …
