AI 中文摘要
非局部量子场论通过在所有动力学项中插入规范和微分同胚协变的整函数调节器来实现微扰紫外有限性。这些算子可视为作用于爱因斯坦方程源的非局部涂抹映射。本文表明，当将负责紫外有限圈的相同整函数调节器应用于点质量的能量动量张量时，所得静态、球对称解会形成一个规则的德西特核心而非曲率奇点。
英文摘要
Nonlocal quantum field theories achieve perturbative ultraviolet finiteness by inserting gauge- and diffeomorphism-covariant entire-function regulators into all kinetic terms. These operators can be viewed as nonlocal smearing maps acting on sources in the Einstein equations. In this paper I show that, when the same entire-function regulator responsible for UV-finite loops is applied to the energy-momentum tensor of a point mass, the resulting static, spherically symmetric solution develops a regular de~Sitter core in place of a curvature singularity.
