Edge-coloured graphs and associated groups / Grasselli, Luigi. - In: RENDICONTI DEL CIRCOLO MATEMATICO DI PALERMO. - ISSN 0009-725X. - STAMPA. - 2-12:(1986), pp. 263-269. ( II Convegno di Topologia Taormina 1984).
Abstract:
We study the relations between group structures associated to edge-coloured graphs described, in previous papers, by A. Donati and A. Vince. A method for directly obtaining a presentation of the fundamental group of a closed 3-manifold from the associated edge-coloured graph is extended to the case of bordered 3-manifolds.
