渐近双曲流形上Einstein约束方程的线性化稳定性

Linearization stability of the Einstein constraint equations on an asymptotically hyperbolic manifold

Romain Gicquaud

摘要:

研究了渐近双曲流形上Einstein约束方程的线性化稳定性。特别地,我们证明了这些方程在非正宇宙学常数的真空解和在一定衰变范围内的Friedman Lemaettre Robertson Walker空间的真空解附近是线性稳定的.我们还证明,这一结果不再是真实的更快的衰变。反例的构造是基于欧氏空间上TT张量的新构造和正能量定理。

英文摘要:

We study the linearization stability of the Einstein constraint equations on an asymptotically hyperbolic manifold. In particular we prove that these equations are linearization stable in the neighborhood of vacuum solutions for a non-positive cosmological constant and of Friedman--Lemaître--Robertson--Walker spaces in a certain range of decays. We also prove that this result is no longer true for faster decays. The construction of the counterexamples is based on a new construction of TT-tensors on the Euclidean space and on positive energy theorems.
