We investigate the applications of slowly varying functions (in Karamata’s sense) to the theory of Markov branching processes. We treat the critical case so that the infinitesimal generating function of the process has the infinite second moment but regularly varies with the remainder. We improve the basic lemma of the theory of critical Markov branching processes and refine the known limit results.
