[For a review of the Russian original (Nauka, Moskva 1971) see Zbl 0231.10001.] This monograph contains several topics from the analytic theory of numbers, which generally are not treated in textbooks on analytic number theory. The first chapter presents background from analysis: the Tauberian theorem of Hardy-Littlewood (also in G. Freud’s version with remainder term) and the Ingham Tauberian theorem for partitions are proved, and Esséen’s inequality, estimating the difference of two distribution functions in terms of their characteristic functions, is given. The second chapter deals with additive problems with an increasing number of summands. Th. Schneider’s lemma on lattice points in parallelepipeds is proved in a probabilistic setting, applications of the local limit theorem of probability theory to number theory are sketched, and Freiman’s theorem concerning an asymptotic formula for the number of solutions of $N=x\quad s\sb 1+\dots +x\quad s\sb n,\quad n\to \infty,\quad n
