我们提出了一类具有孤立子解的场论，其中拓扑缺陷可以在它们与相等或更高维的其他缺陷相交时结束。这样的组态可以称为狄利克雷拓扑亏损，类似于弦理论的D膜。我们的讨论集中在3+1维中具有规范对称性或整体对称性的标量场理论中的缺陷;考虑的缺陷类型包括墙在墙上，弦在墙上，弦在弦上。{版权} {美国物理学会}
We propose a class of field theories featuring solitonic solutions in which topological defects can end when they intersect other defects of equal or higher dimensionality. Such configurations may be termed {open_quotes}Dirichlet topological defects,{close_quotes} in analogy with the D-branes of string theory. Our discussion focuses on defects in scalar field theories with either gauge or global symmetries, in 3+1 dimensions; the types of defects considered include walls ending on walls, strings on walls, and strings on strings. {copyright} {ital 1998} {ital The American Physical Society}
