Query: A Nonlinear Evolution Equation in an Ordered Banach Space, Reconsidered   Results of a previous paper [Commun. Contemp. Math., 09 (2007) 217-251] on
the existence of solutions to a nonlinear evolution equation in an abstract
Lebesgue space, arising from kinetic theory, are re-obtained in the more
general setting of a real ordered Banach space, with additive norm on the
positive cone, which is not necessarily a (Banach) lattice.
  In addition, an easily correctable technical error in the aforementioned
paper is pointed out, and repaired.
