This paper is a survey of some recent authors' results concerning the function $\psi(G)$, which is the sum of orders of elements of a finite group. More precisely, the authors consider the question how the value of $\psi(G)$ affects the structure of $G$.
Keywords: order of element of group, finite group.
Mots-clés : solvable group
