标题： Quantization of the Szekeres spacetime through generalized symmetries

摘要： 我们展示了量子修正对Szekeres时空的影响，这是一个对于研究宇宙暴胀前时期的非均匀性具有重要意义的系统。 该研究是在存在对称性的规范量子化框架下进行的。 我们构建了一个有效经典拉格朗日量，并在波函数上施加其经典运动积分的量子版本。 量子解的解释方案采用的是Bohm力学，这样可以避免量子宇宙学中的幺正性问题。 我们在这一背景下讨论了我们的结果。 显示英文摘要

摘要： We present the effect of the quantum corrections on the Szekeres spacetime, a system important for the study of the inhomogeneities of the pre-inflationary era of the universe. The study is performed in the context of canonical quantisation in the presence of symmetries. We construct an effective classical Lagrangian and impose the quantum version of its classical integrals of motion on the wave function. The interpretational scheme of the quantum solution is that of Bohmian mechanics, in which one can avoid the unitarity problem of quantum cosmology. We discuss our results in this context.
