S. Simons, ON STEADY-STATE SOLUTIONS OF THE COAGULATION EQUATION (VOL 26, PG 1259, 1993), Journal of physics. A, mathematical and general, 29(5), 1996, pp. 1139-1140
Earlier work on time-independent solutions of the coagulation equation
is generalized to yield explicit solutions for any kernel of the form
P(u, v) = T(u)T(v)Q(u, v) where Q is a homogeneous function of u and
v.
