反de Sitter时空中的非拓扑孤立子
Nontopological Solitons in Anti de Sitter Spacetimes
-
摘要: 讨论了反de Sitter时空中的非拓扑孤立子,利用渐近级数展开法,证明了在该时空中,只有势函数满足一定条件的非拓扑孤立子才能存在。Abstract: The nontopological scalar solitons are investigated in an anti de Sitter spacetime.The result shows that only the solitons which obey the necessary conditions can exist in the background by means of the series expansion.
