摘要
We consider mass-conserving self-similar solutions of Smoluchowski's coagulation equation with product kernel of homogeneity 2 lambda is an element of (0, 1). We establish rigorously that such solutions exhibit a singular behavior of the form x(-(1+2 lambda)) as x -> 0. This property had been conjectured, but only weaker results had been available up to now.
