摘要：

We derive and discuss black-hole solutions to the gravitating O(3) sigma model in (2 + 1) dimensions. Three different kinds of static black holes are found. One of these resembles the static BTZ black hole, another is completely free of singularities, and the last type has the same Penrose diagram as the (3 + 1)-dimensional Schwarzschild black hole. We also construct static and dynamical multi-black-hole systems.
