标题： Global embeddings of scalar-tensor theories in (2+1)-dimensions

摘要： 我们得到四个无电荷和带电的标量-张量理论在(2+1)维中的(3+3)或(3+2)维全局平坦嵌入，这些理论的参数为B或L，它们是Banados-Teitelboim-Zanelli (BTZ) 黑洞的非平凡修改版本。极限情况B=0或L=0恰好退化为BTZ黑洞的全局嵌入闵可夫斯基空间(GEMS)解。 显示英文摘要

摘要： We obtain (3+3)- or (3+2)-dimensional global flat embeddings of four uncharged and charged scalar-tensor theories with the parameters B or L in the (2+1)-dimensions, which are the non-trivially modified versions of the Banados-Teitelboim-Zanelli (BTZ) black holes. The limiting cases B=0 or L=0 exactly are reduced to the Global Embedding Minkowski Space (GEMS) solution of the BTZ black holes.
