Cocycle invariants of codimension 2 embeddings of manifolds
We consider the classical problem of a position of n-dimensional manifold Mⁿ in . We show that we can define the fundamental (n+1)-cycle and the shadow fundamental (n+2)-cycle for a fundamental quandle of a knotting . In particular, we show that for any fixed quandle, quandle coloring, and shadow quandle coloring, of a diagram of Mⁿ embedded in we have (n+1)- and (n+2)-(co)cycle invariants (i.e. invariant under Roseman moves).

Compactification via le spectre réel d’espaces des classes de représentation dans SO
Soit un groupe de type fini non élémentaire. On note l’ensemble des structures hyperboliques de dimension sur . peut se réaliser comme fermé dans un espace semi-algébrique qui admet une compactification naturelle par le spectre réel. On note le compactifié via le réel de . L’objet de cet article est de décrire les points ajoutés dans . La compactification obtenue de cette manière permet d’interpréter “les points frontières” comme des représentations de dans où est un corps réel...
