We investigate the linear and semilinear massive Klein-Gordon equations in geometrical frameworks of type "Conformal Cyclic Cosmology" of R. Penrose, or "Singular Bouncing Scenario" as well. We give sufficient conditions on the decay of the mass to the fields be able to propagate across the Big-Bang.

大爆炸前宇宙学中大量标量场的传播

我们在 R. Penrose 的“共形循环宇宙学”类型或“奇异弹跳场景”类型的几何框架中研究线性和半线性大规模 Klein-Gordon 方程。我们为能够在大爆炸中传播的场提供了质量衰减的充分条件。
