A Toponogov-type comparison theorem for locally CAT(k) spaces
This paper studies the Toponogov-type properties of locally Cartan-Alexandrov-Toponogov (CAT(k)) spaces． Based on the globalization theorem for Alexandrov spaces with a lower curvature bound, a Toponogov-type comparison theorem for locally CAT(k) spaces is presented, which proves the globalization theorem for locally CAT(k) spaces．
