论文摘要
在静止的框架真空中考虑了定位器扩展宇宙的标量和纺纱场的扁平限制的问题，在该真空中，频率在休息框架中分开，就像在特殊相对论中一样。为了获得Minkowskian扁平限制，这些磁场的基本解决方案的阶段是正规化的。在其余框架真空中给出了标量模式函数或达到自然平坦限制的狄拉克纺纱器的新表达式，并提出了合适的近似公式。以这种方式，正确定义了整个量子理论的固定极限，因为一个粒子算子倾向于特殊相对论。
The problem of the flat limits of the scalar and spinor fields on the de Sitter expanding universe is considered in the rest frame vacuum where the frequencies are separated in rest frames as in special relativity. The phases of the fundamental solutions of these fields are regularized in order to obtain Minkowskian flat limits. New expressions of scalar mode functions or Dirac spinors reaching natural flat limits are given in the rest frame vacuum and suitable approximate formulas are proposed. In this manner the flat limit is correctly defined for the entire quantum theory since the one-particle operators tend to those of special relativity.
