%0 Journal Article %T M¨¦thodes aux grandes ¨¦chelles pour mesurer la topologie (globale) de l'Univers %A Boudewijn F. Roukema %J Physics %D 1998 %I arXiv %X Several recent large length scale methods of detecting the topology of the Universe are briefly reviewed. Three-dimensional methods include those of Lehoucq, Luminet & Lachi\`eze-Rey (1996), Roukema (1996) and Roukema & Edge (1997). The two-dimensional ``circles'' method of Cornish, Spergel & Starkman (1996b) is also mentioned. %U http://arxiv.org/abs/astro-ph/9801225v1
