摘要

简要回顾了当明确打破微分同构不变性的固定非动力背景包含在引力理论中时可能发生的问题。对标准模型扩展(SME)的含义进行了总结，包括最近的结果显示如何修改SME以适应这种固定的非动态背景。

Explicit Diffeomorphism Breaking, No-Go Conditions, and the Gravity Sector of the SME

A brief recap is given of issues that can occur when fixed nondynamical backgrounds that explicitly break diffeomorphism invariance are included in gravity theories. Implications for the Standard-Model Extension (SME) are summarized, including recent results showing how the SME can be modified to accommodate such fixed nondynamical backgrounds.
