在相互作用流体理论的框架下，我们给出了描述与辐射耦合的膨胀子场演化的Boltzmann方程的数值解。我们研究了在慢滚状态下系统的行为，当方程组中包含了附加的随机源项时，我们恢复了以前在热膨胀情形下得到的宇宙学微扰的表达式。
Within the framework of the interacting fluid formalism, we provide the numerical solution to the Boltzmann equation describing the evolution of an inflaton field coupled to radiation. We study the behavior of the system during the slow-roll regime, in the case in which an additional stochastic source term is included in the set of equations, and we recover the expression for the cosmological perturbations previously obtained in the Warm inflation scenarios.
