摘要:
给出了一般星值方程的形式解,研究了其性质,并给出了量子相空间中星超曲面的几何解释。我们的方法处理离散和连续光谱在一个统一的方式,包括一个系统的处理非对角stargenfunctions。利用这一方法得到了海森堡图象下Wigner量子力学的完整形式解,并给出了任意维相空间变量的二次Hamilton星函数的一般公式.各种系统,然后用来说明前者的结果。
英文摘要:
The formal solution of a general stargenvalue equation is presented, its properties studied and a geometrical interpretation given in terms of star-hypersurfaces in quantum phase space. Our approach deals with discrete and continuous spectra in a unified fashion and includes a systematic treatment of non-diagonal stargenfunctions. The formalism is used to obtain a complete formal solution of Wigner quantum mechanics in the Heisenberg picture and to write a general formula for the stargenfunctions of Hamiltonians quadratic in the phase space variables in arbitrary dimension. A variety of systems is then used to illustrate the former results.
