AI中文摘要:
双组分Becker-Döring模型是一个二维凝聚-碎裂方程,描述了由两种不同类型单体通过单体相互作用生长和收缩而构成的团簇动力学。我们证明了解的存在性和质量守恒,并给出了关于唯一性的部分结果。此外,在细致平衡假设下,我们证明了熵方程,随后对平衡态和相对熵进行了详细研究。我们能够在固定I型和II型质量的序列下确定所有相对熵的最小值,并在弱*拓扑下完全描述极小化序列。
英文摘要:
The two-component Becker-Döring model is a two-dimensional coagulation-fragmentation equation that describes the dynamics of clusters built from two different types of monomers growing and shrinking through monomer interaction. We show the existence and mass conservation of solutions and give a partial result regarding uniqueness. Furthermore, we prove under the assumption of detailed balance the entropy equation, followed by a detailed study of the equilibrium states and relative entropies. We can determine the minimum of all relative entropies under sequences of fixed Type I and Type II masses and fully describe the minimising sequences in the weak* topology.
