摘要：

描述了PT对称哈密顿量H=p^2+V（x）概念的推广。它使用解析势V（x）（具有奇点）和PT对称渐近边界条件的广义概念。非平凡滑降被定义为沿拓扑非平凡路径的坐标运行在几个黎曼片的波函数。

英文摘要：

A generalization of the concept of PT-symmetric Hamiltonians H=p^2+V(x) is described. It uses analytic potentials V(x) (with singularities) and a generalized concept of PT-symmetric asymptotic boundary conditions. Nontrivial toboggans are defined as integrated along topologically nontrivial paths of coordinates running over several Riemann sheets of wave functions.
