量子力学中的数学惊奇和狄拉克形式

Mathematical surprises and Dirac's formalism in quantum mechanics

F. Gieres

摘要:

通过一系列简单的例子,我们说明了如何缺乏数学关注可以很容易地导致令人惊讶的数学矛盾的波动力学。基本的数学概念,允许一个精确的理论制定,然后总结,并显示它们如何导致上述问题的阐明和更深入的理解。在强调波动力学和量子力学的其他公式,即矩阵力学和狄拉克的抽象希尔伯特空间公式之间的等价性后,我们致力于后一种方法的第二部分:我们讨论的问题和缺点,这种形式主义,以及在这方面的狄拉克介绍的bra和ket符号。最后,我们指出如何解决或至少避免所有这些问题。

英文摘要:

By a series of simple examples, we illustrate how the lack of mathematical concern can readily lead to surprising mathematical contradictions in wave mechanics. The basic mathematical notions allowing for a precise formulation of the theory are then summarized and it is shown how they lead to an elucidation and deeper understanding of the aforementioned problems. After stressing the equivalence between wave mechanics and the other formulations of quantum mechanics, i.e. matrix mechanics and Dirac's abstract Hilbert space formulation, we devote the second part of our paper to the latter approach: we discuss the problems and shortcomings of this formalism as well as those of the bra and ket notation introduced by Dirac in this context. In conclusion, we indicate how all of these problems can be solved or at least avoided.
