摘要：

We generalize the class if all compact 3-manifolds to a class of new objects called virtual 3-manifolds. Each virtual 3-manifold determines a 3-manifold with singularities of the type Con(RP2) and may be presented by a triangulation as well as by a special spine. Many properties and invariants of 3-manifolds can be extended to the virtual ones. We restrict ourselves to mentioning Turaev-Viro invariants and two-sheeted branched coverings of virtual 3-manifolds.
