摘要：

We derive and analyse exact static solutions to the gravitating O(3) sigma model with a cosmological constant in (2 + 1) dimensions. Both signs of the gravitational and cosmological constants are considered. Our solutions include geodesically complete spacetimes, and two classes of black holes.
