系统地评述了基于不定度量希尔伯特空间的量子场论的一些最新进展。广泛讨论了各种问题（如下面的目录所示）。主题的选择，但是，取决于本作者的兴趣;未描述的主题不一定是不重要的。对有限维不定度量空间作了几乎完全的论述。在不定度规量子场论中，详细讨论了物理S-矩阵的解释和唯一性问题。还包括一些新的结果和评论的各种现有的理论。其中一些是只有一个费曼积分的场论的建设，批评意见的量子化一个纯粹的量子质量场和批评重整化程序的古普塔-布莱布雷量子电动力学。（auth）
Some recent progress in the quantum field theory based on the indefinite- metric Hilbert space is reviewed in a systematic way. Various problems (as shown in the table of contents below) are discussed extensively. The selection of topics is, however, dependent on the present author's interest; undescribed topics are not necessarily meant to be unimportant. An almost complete exposition is given concerning the finite-dimensional indefinite-metric space. On the indefinite-metric quantum field theory, the problem of interpretation and the unltarity of the physical S-matrix are discussed in detail. Also included are a number of new results and remarks on various existing theories. Some of them are construction of a field theory having only one Feynman integral, critical remarks on the quantization of a purely imaginary-mass field and a criticism of the renormalization procedure of the Gupta-Bleuler quantum electrodynamics.
