摘要:
薛定谔哈密顿量的高阶超对称伙伴可以通过迭代一个简单的有限差分方程对应的Baecklund变换显式构造。该方法可以完全取代Crum行列式。它的限制,差分情况下提供了一些新的操作优势。
英文摘要:
The higher order supersymmetric partners of the Schroedinger's Hamiltonians can be explicitly constructed by iterating a simple finite difference equation corresponding to the Baecklund transformation. The method can completely replace the Crum determinants. Its limiting, differential case offers some new operational advantages.
