In this paper, we develop explicit and semi-implicit second-order high-resolution finite difference schemes for a structured coagulation-fragmentation model formulated on the space of Radon measures. We prove the convergence of each of the two schemes to the unique weak solution of the model. We perform numerical simulations to demonstrate that the second order accuracy in the Bounded-Lipschitz norm is achieved by both schemes.
在本文中，我们针对在拉东测度空间上构建的结构化凝聚 - 破碎模型，开发了显式和半隐式二阶高分辨率有限差分格式。我们证明了这两种格式中的每一种都收敛于该模型的唯一弱解。我们进行了数值模拟，以证明这两种格式在有界 - 利普希茨范数下均达到二阶精度。
