In this paper give a survey about L^2-invariants focusing on 3-manifolds.

Paul Tee

We classify maximal systems of arcs which intersect at most once on the 4-punctured sphere.

In this paper we look at which Alexander and Markov theories can be defined for generalized knot theories

Hiroshi Matsuda

Ng constructed an invariant of knots in ${\mathbb{R}}^3$, a combinatorial knot contact homology. Extending his study, we construct an invariant of surface-knots in ${\mathbb{R}}^4$ using marked graph diagrams.

We prove that the reduced 2-coloured Khovanov homology detects the trefoil, using a spectral sequence to knot Floer homology.

Hom gives an example of a knot with vanishing Upsilon invariant but nonzero epsilon invariant. We build more such knots that are linearly independent in the smooth concordance group.

We give a volume formula of hyperbolic knot complements using twisted Alexander invariants.

Francesca Aicardi

In this note we define a polynomial invariant for colored links by a skein relation. It specializes to the Jones polynomial for classical links.

Federico Franceschini

We prove the Proportionality Principle for the Lipschitz simplicial volume without any restriction on curvature. Our argument is based on the construction of a suitable \emph{pseudostraightening} for simplices.

Pedro Lopes

We prove that if a link admits non-trivial (2k+1)-colorings, with prime 2k+1>7, it also admits non-trivial (2k+1)-colorings not involving colors 2k, 2k-1, nor k.
