The gravitational dynamics of a collapsing matter configuration which is simultaneously radiating heat flux is studied in f(R) gravity. Three particular functional forms in f(R) gravity are considered to show that it is possible to envisage boundary conditions such that the end state of the collapse has a weak singularity and that the matter configuration radiates away all of its mass before collapsing to reach the central singularity.

在f（R）引力下的引力坍缩恒星

在f（R）重力下研究了同时散发热通量的坍塌物质构型的重力动力学。认为f（R）引力的三种特殊函数形式表明，有可能设想边界条件，使得坍塌的最终状态具有弱的奇异性，并且物质构型在塌陷之前辐射出它的全部质量。中心奇点。
