Matveev's complexity of classical and virtual 3-manifolds.
Résumé:
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.
