论文摘要
我们发现，对于各种孤子过程，相应的规范模量空间可以具有一个边界，该边界可以在有限的时间演化中访问。我们表明，这种边界不是模量空间方法的失败，而是物理含义。在我们的示例中，它对应于有限的时间后的碰撞扭结和抗京克的完全an灭。我们进一步发现，靠近边界的解决方案具有近似的自相似形式。
We find that for various solitonic processes the corresponding canonical moduli space can have a boundary which is accessible in a finite time evolution. We show that such a boundary is not a failure of the moduli space approach but has a physical meaning. In our example, it corresponds to the complete annihilation of a colliding kink and antikink after a finite time. We further find that, close to the boundary, the solutions have an approximate self-similar form.
