一类广义Lame方程的拟双周期解

Quasi-doubly periodic solutions to a generalized Lame equation

Michael Pawellek

摘要:

考虑了具有五个自由参数的广义Lame方程的代数形式。通过引入推广的Jacobi椭圆函数,我们将该方程转化为具有(拟双)周期势的一维非定常Schroedinger方程。我们表明,只有一组有限的积分值的五个参数的拟双周期的特征函数表示的广义雅可比函数存在。为此,我们还建立了一个关系到广义因斯方程。

英文摘要:

We consider the algebraic form of a generalized Lame equation with five free parameters. By introducing a generalization of Jacobi's elliptic functions we transform this equation to a 1-dim time-independent Schroedinger equation with (quasi-doubly) periodic potential. We show that only for a finite set of integral values for the five parameters quasi-doubly periodic eigenfunctions expressible in terms of generalized Jacobi functions exist. For this purpose we also establish a relation to the generalized Ince equation.
