摘要:

如果(1+1)维标量场具有服从一阶BPS方程的孤子解,那么,一般来说,可以找到无限多个相关的具有服从密切相关的BPS方程的BPS孤子的场论。我们指出,这一事实可以理解为一个简单的后果,一个适当的广义概念的自我二重性。我们表明,这种自对偶框架使我们能够推广到更高的维度,从已知的解决方案的新的孤子的建设。通过执行简单的场变换,我们的程序允许我们与不同的拓扑性质的孤子。我们提出了几个有趣的例子,这样的孤子在二维和三维。

英文摘要:

If a scalar field theory in (1+1) dimensions possesses soliton solutions obeying first order BPS equations, then, in general, it is possible to find an infinite number of related field theories with BPS solitons which obey closely related BPS equations. We point out that this fact may be understood as a simple consequence of an appropriately generalised notion of self-duality. We show that this self-duality framework enables us to generalize to higher dimensions the construction of new solitons from already known solutions. By performing simple field transformations our procedure allows us to relate solitons with different topological properties. We present several interesting examples of such solitons in two and three dimensions.
