时空度规作为瞬时模空间的Fisher-Rao“信息度规”的想法已经在一些场论中得到了检验,例如Yang-Mills理论和非线性σ模型。在本文中,我们报告了从大量Klein-Gordon场(线性σ模型)的非平凡解中可以得到平坦欧几里得度规或闵可夫斯基度规,而不是从瞬子模空间中一般出现的反德西特度规。这种从简单场论出发的平面空间的实现,将有助于研究将时空几何与信息几何联系起来的思想。
The idea that a space-time metric emerges as a Fisher-Rao "information metric" of instanton moduli space has been examined in several field theories, such as the Yang-Mills theories and nonlinear σ models. In this paper, we report that the flat Euclidean or Minkowskian metric, rather than an anti-de Sitter metric that generically emerges from instanton moduli spaces, can be obtained as the Fisher-Rao metric from a nontrivial solution of the massive Klein-Gordon field (a linear σ model). This realization of the flat space from the simple field theory would be useful to investigate the ideas that relate the space-time geometry with the information geometry.
