连续的物质创造和宇宙的加速：重播
Continuous matter creation and the acceleration of the universe: a replay
摘要：
在最近的一份说明（arXiv：1012.5069）中，本作者对加速宇宙中密度波动的演变（包括物质创造）进行的研究受到了批评。这种批评是基于牛顿背景没有“加速”的事实，从而使线性分析的结论无效。我们表明，我们的线性方程充分描述了一个加速宇宙中的压力与创造过程是恒定的，相当于$Λ$ CDM宇宙学模型。因此，我们先前的结论保持不变。
英文摘要：
In a recent note (arXiv:1012.5069), the investigation performed by the present authors on the evolution of density fluctuations in an accelerated universe including matter creation was criticized. The criticism is based on the fact that the Newtonian background is not "accelerating", invalidating the conclusions of the linear analysis. We show that our linear equations describe adequately an accelerating universe in which the pressure associated to the creation process is constant, a model equivalent to the $Λ$CDM cosmology. Thus, our previous conclusions remain unchanged.
