| Titre ||On Matveev’s complexity of classical and virtual 3-manifolds|
| Horaire||11:00 à 12:00|
| Résume||The most useful approach to a classication of 3-manifolds is the complexity theory founded by S. Matveev. Exact values of complexity are known for few infinite series of 3-manifold. We present the results on complexity for new infinite series of hyperbolic 3-manifolds with boundary. Also we introduce a notion of complexity for virtual 3-manifolds.
